Introduction and Test Series Announcement
Udy Choudhary welcomes viewers to Agriculture & GK's YouTube channel. The session will cover previous years' CUET PG question papers with detailed solutions and discussions. For students preparing for the CUET PG Agroforestry exam, a test series is available to enhance preparation. This test series includes over 30 full-length and subject-wise tests, providing a real-time exam experience with relevant questions. It also offers complete analysis with all India rank, percentile, time spent, toppers comparison, and section-wise detailed reports. The test series contains over 1500 important MCQs and is priced at ₹499.
Question 1: Fungal Decay of Wood
The first question asks which statements are correct regarding fungal decay of wood. The options include: Soft rot is caused by fungi related to molds; decay results in abnormal coloration; the growing stage consists of thread-like hyphae; and both dry and wet wood are vulnerable. All four statements are correct. Soft rot is indeed caused by fungi related to molds, decay leads to abnormal coloration, fungi grow thread-like hyphae, and both very dry and very wet wood are susceptible to fungal decay. Therefore, option C, stating that all four options are correct, is the right answer.
Question 2: Self-Sufficient and Self-Regulating Ecosystems
The second question identifies which ecosystem is self-sufficient and self-regulating. The options are marine, grassland, desert, and pond ecosystems. A pond ecosystem is self-sufficient because it contains abiotic factors like water, dissolved oxygen, and nutrients, as well as producers like phytoplankton and algae, and decomposers like bacteria and fungi. It is also self-regulating, maintaining equilibrium through population control and nutrient cycling. For example, if algae population increases, zooplankton population also increases to consume the algae, thus maintaining balance.
Question 3: Plant Stages and Water Exposure
The third question asks about the plant stage where roots are in water, but most of the plant is exposed to air. The options include sed meadow, rooted floated, rooted submerged, and lead swamp stages. In the rooted floated stage, the roots are in water or mud, but the leaves are outside the water, like in the lotus plant. The lead swamp stage fits the description best, where the root is in a marshy area, and the rest of the plant is exposed to air.
Question 4: Software Components of GIS
The fourth question asks which of the following is not a software component of GIS (Geographic Information System). GIS components include software, hardware, data, and people. Options given are graphical database, transformation, and plotter. Plotter is a hardware component, while graphical database and transformation are software components.
