Practice questions testing deep understanding of food chains, energy flow, and ecological balance.
Q1. In a grassy savanna, the local government decides to kill all the lions to protect the deer population. Five years later, the area turns into a barren wasteland. Analyze the food web to explain why saving the deer destroyed the ecosystem.
Q2. Assertion (A): The amount of energy available at the top of a food chain (e.g., to an eagle) is much less than the energy available at the bottom (e.g., to the grass). Reason (R): According to the 10% law, 90% of energy is lost as heat or used for metabolic processes at each trophic level, leaving only 10% to be passed to the next level.
