Ecosystem in Tamil | Ecological Succession in Tamil | Environmental Science and Sustainability Tamil

0:00 [Music] welome students welcome to for academy eem information so first ecosystem so eological succession so ecology definition

1:01 ecology the study of the distribution and abundance of organisms so of energy and materials between abiotic and biotic ecosystem so a biotic now non- living things biotic living things so in the non Liv things living things the ecology definition next next eem

1:51 definition the ecosystem is the interdependence of living creatures and their surroundings in a certain unit of space relationship dep e and ecosystem contains all of the biotic atic and non- living components bio living non Liv

2:38 things EOS definition next who coin the term ecosystem eem the Wordly interaction between biotic and abiotic components of the environment at a specific Place bio living things non Liv things micro next study of ecosystem ecosystem research is

3:24 concerned with how neighboring species interact with one another and how energy flow between how energy flow between through the ecosystem chain of creatures so the ecosystem importance of

4:09 ecosystem it aids in the ecosystem capacity to keep the tropical levels in appropriate bance energy flow it is crucial for supporting biological system and preserving balance as well as as for managing energy flow and ecological process so crucial important okay so important

5:00 next why is ecosystem necessary ecosystem conserves matter and the energy and the energy flowing through f l w typing mistake flowing through the system is balanced as it move from one creat to the next and matter is recycled ecos

5:45 ecosystem size varies and it can be as little as aases or huge as an ocean so ecosystem little as or use as Anan structure of an ecosystem etic components biotic components atic and adic climatic rain light wind temperature Ada soil PH minerals

6:32 topography topography biotic components prods primary consum secondary consumers tertiary consumer quary consumer primary largee next abiotic

7:18 components abiotic components the physiochemical environment are basic inorganic elements and compound components example soil water oxygen calcium carbonate phosphate and a variety of organic compounds bio comps biotic components these are all live creatures found in the environment Liv mostly environment

8:04 bi autops these are chlorop compounds and solar energy absorption okay so in the inorganic a biotic comp next biotic components next etot trops these are organisms that cannot produce their own food

8:54 so fots macro consumers orm that eat otheres consume plants de go the example primary secondary consumers example cat snakes secondary consum secondary example tiger lion

9:53 om next sapr trops micro consumers or decomposers these are bacteria and fungi that break down complex dead organic materials into simple inorganic form biotic components next functions of ecosystem total of five functions first one productivity

10:40 second one decomposition third one energy flow fourth one food chain food web ecological succession and fifth one biog geochemical process so one by one detail so first productivity it is the rate of biom production it is stated in units of G sare kilo calories Square yes so primary productivity is determined by how quickly organic matter is produced duryn

11:35 gpp R net primary productivity prod producers gpp gross primary productivity next decomposition composes convert complex organic matter into inorganic elements complex

12:22 organic raw material for decomposition and includes dead plant remnants warm wet environment encourages decomposition process start next energy flow the primary source of energy needed by all living things is the chemical energy found in the food

13:07 along the food chain this energy transfer to various tropical levels flow next thams second energy is squandered more and more as it transfer

14:16 next next energy flow in your food chain f l w okay typing FB flow energy flow in a food chain ad to the 10 percentage law states that only 10 per of energy is transferred from one tropic level to the next and the remaining 19 90% is lost to the atmosphere

15:13 EX food chain

15:59 food chain refers to chain of creatures that transfer food energy from producer to Consumer including Heros cariv and decompos soain types of food chain grazing food chain detrus food chain parasitic food

16:46 chain pH micm organisms fishes so the fishes z z theing starting with grass begin with green plants which provide food for heror so heror animal SK

17:31 PLS grasses which in provide food for Predators next detrus food chain these start with dead organic materials and go on to detrivore creatures which produce food for protozoa Carnivor and other species the detritus food chain dead organic food chain for parasite parasite

18:40 teres so it start with the host and end with parasitic food chain food web chain chain relation food web is an interconnection of food chain it comprises of many chain removal of one group of organisms not at all disturb

19:35 in members of higher tropical level feed upon many organisms of lower tropical level next the food web grass m rabbit Fox owl frog grasshopper bird snake H chain

20:21 organisms okay next ecological succession it is defined as a shift in the community in which new population of species progressively replace existing one succession yeah shift in the community in which new population of species progressively replacing

21:12 existing next difference between primary succession secondary succession primary sucession so begin with no life so stage second Su follows removal of existing M come first so

21:59 stage primary SU St second sucession next fifth one biog geochemical process bio geochemical Cycles also

22:47 known as nutrition cyle nutrition cycle it describes the movement of chemical elements through different media such as atmosphere soil rocks bodies of water and organisms so chemicals nitrogen cycle in the biog geochemical Cycles keep Essential Elements available TOs and other

23:39 orms matter moves through different media and atoms May react to form new molecules but the amount of matter remains constant matter gas so matter the bio geochemical cyes of four elements carbon cycle nitrogen cycle

24:24 phosphorus cycle CLE C so the cyes elements bio geochemical process function eem next next types of ecosystem so ecos two types of natural ecosystem manmade or artificial ecosystem in the manmade artificial

25:21 conditions manmade or artificial ecosystem next natural ecosystem the two types of terrestrial ecosystem aquatic ecosystem terrestrial normal land aquatic water terrestrial EOS three tyes Forest grassland Desert Aquatic ecos Marine water fresh water so first one forest ecosystem yeah forest ecosystem is a functional unit or a system which comprises of soil trees insects animals Birds

26:08 man interacting ecos your Forest is a large and complex ecosystem and hence has a greater species diversity so for different atic components refers to inorganic materials like water producers ched

26:55 consumers her Carn Forest e species composition stratification so first one species composition and it refers to the identification and enumeration of the plant and animal species of a forest ecosystem

27:46 stratification it refers to the vertical distribution of different species which occupy different levels in the forest ecosystem forest ecosystem herbs grasses bottom grass next grassland ecosystem grasslands are one of the

28:33 intermediate stages in ecological succession and cover a part of the land on all the attitudes and latitudes at which climatic and soil conditions do not allow growth of trees so grassland cover areas where rainfall is usually low soil depth and quality is poor so grassland ecosystem the low rainfall prevent the growth of numerous trees but is sufficient to support the growth of grass cover during the

29:26 monsoon eem next next producers the grassland e prims sheep deer rabbit buffal insect insect dis derus cinella lepto Cora some terites and primary consumers in the grassland EOS next grassland ecos secondary

30:11 consum these are caros Carnivor that feed on primary consumers Heros heror cariv animals like foxes jackal snakes frogs liards Birds e tertiary consumers these include Hogs which feed on secondary consumers decompos Bia dead and D matter M fungi decompos

30:59 mu pic ASP Rus the grassland ecos next desert ecosystem yeah desert ecosystem is defined the typing mistake d e f i n e d defined by interactions between organisms the climate in which they live and any other non-living influences on theit sot e deserts are regions that are generally associated with warm temperature however

31:45 cold desert also exist desert ecosystem is the driest ecosystem of the Earth this is the reason it has less vegetation and less diversity of Life desert next desert ecos characteristics first AR environment Des temp sparse vegetation due to the lack

32:34 of water vegetation is pass and is adapted to conserve water so extreme temperature variations reason reason I wind velocity strong winds in desert lead to erosion shaping unique landforms like Sands

33:31 next Marine water ecosystem So Cal okay ocean the interaction between the living plants and animals and non-living things within the Marine culture are commonly known as Marine ecosystem e inter Mar water e the Marine ecosystem covers More than 70% of the Earth surface the Marine ecosystem provide a

34:16 wide range of habitate for fluid typing mistake l o r okay and Fa of the Marine aquatic system that ranges from seashore to the deep sea B so Marine ecosystem starting stage interaction water e it is a home for millions of species

35:02 next Marine water ecos next topic carbon sequestration meaning the world's ocean act as a critical carbon sink absorbing and storing vast amount of carbon dioxide from the atmosphere so atmosphere this process helps regulate Global CL climate patterns and mitigate the effects of climate change

35:51 so next Marine water EOS coral reef coral reefs are vibrant underwater ecosystem formed by accumulation of coral skeleton these Reaves are biodiversity hsing with colorful fishes M other Marine leaf jellyish mang Forest mang forest grow in coastal areas

36:37 with the salty water the sudar okay West Tangled Roots nurseries for young fish and protect Coastline from erosion so mang Forest okay so the mang Forest

37:27 Tang next seagrass mows seagrass mows are underwater grassland that provide important feeding and breeding ground for many marine species including turtles andong so next kelp forest kelp forest are found in cold nutrition Rich Waters and are

38:13 characterized by towering kelp plants they provide shelter for wide range of marine creatures atly

38:58 fresh waterer ecosystem ecosystem the fresh water is found in the form of ponds pond ecosystem Lake ecosystem stream ecosystem frozen water ecosystem other than and fr water e the fresh waterer ecosystem play an Ro in biodiversity so biodiversity fres water however it is less extensive fresh water next pond ecosystem pond ecosystem is a freshwater

39:46 ecosystem on which living organism relay for the survival and ponds are shallow water bodies going about 12 to 15t deep due to enough light penetration Pond can facilitate plant growth next Pond stratification pond ecosystem Zone first loral Zone limnetic

40:36 Zone and then profundal Zone the moon zone so first literal zone High light penetration dominated by plon the deepest region is a profund Zone dominated bys and has no

41:22 light so first ecology definition next eological definition eem definition who coined the term ecosystem study of ecosystem importance of ecosystem why is ecosystem necessary structure of an ecosystem abiotic components biotic components autot trops atrops herbivores primary Carnivor

42:08 secondary Carnivor omnivores sapot trops functions of ecosystem productivity decomposition energy flow food chain food web ecological sucession biog geochemical process so productivity decomposition energy flow energy flow loss of thermodynamics 10 percentage La MIM topic energy flow food chain types of food chain grazing food chain detritus food chain food chain for parasites food web so food web kind structure example

42:57 ecological succession difference between primary succession secondary succession biog geoc chemical process types of ecosystem forest ecosystem structural types species composition stratification species composition stratification explanation grassland ecosystem produces primary consumers secondary consumers tertiary consumer decomposes in grassland ecosystem next desert ecosystem what are the characteristics of desert

43:43 ecosystem next Marine water ecosystem carbon sequestration coral reef mangr Forest seagrass made skelp Forest freshwater ecosystem pond ecosystem Pond stratification layers students ecosystem flow eological sucession functions of ecosystem watch other episodes in the appropriate playlist for Academy strength success Clarity w
