Environment and Ecology Questions and Answers – Page 4

Correct Answer: Option B — Food Chain. Food Chain is correct because it is producers form the base of most grazing food chains. Food Chain is also specifically associated with consumers occupy successive trophic levels. Two additional identifying facts are that Food Chain is consumers occupy successive trophic levels and Food Chain is associated with interconnected food chains form a food web. Why the other options are incorrect: • Option A — Biodiversity Hotspot: Biodiversity Hotspot is the concept prioritizes globally important conservation regions. It is incorrect here because its separate identifying association is parts of the Himalaya and Western Ghats-Sri Lanka hotspots occur in India. • Option C — Wetland: Wetland is marshes, floodplains, lakeshores and mangrove areas can be wetlands. It is incorrect here because its separate identifying association is wetlands can store floodwater and support specialized biodiversity. • Option D — Environmental Impact Assessment: Environmental Impact Assessment is baseline conditions and predicted impacts are assessed. It is incorrect here because its separate identifying association is mitigation and environmental-management measures are considered. Exam Takeaway: Connect Food Chain with “producers form the base of most grazing food chains” and “consumers occupy successive trophic levels”.

Correct Answer: Option A — Food Chain. Food Chain is correct because it is a linear sequence showing transfer of food energy. Food Chain is also specifically associated with producers form the base of most grazing food chains. Two additional identifying facts are that Food Chain is consumers occupy successive trophic levels and Food Chain is associated with interconnected food chains form a food web. Why the other options are incorrect: • Option B — Biodiversity Hotspot: Biodiversity Hotspot is a region combining exceptional endemism with severe habitat loss. • Option C — Wetland: Wetland is land where water controls ecological conditions for significant periods. It is incorrect here because its separate identifying association is marshes, floodplains, lakeshores and mangrove areas can be wetlands. • Option D — Environmental Impact Assessment: Environmental Impact Assessment is a process for examining likely environmental effects before project decisions. It is incorrect here because its separate identifying association is baseline conditions and predicted impacts are assessed. Exam Takeaway: Connect Food Chain with “a linear sequence showing transfer of food energy” and “producers form the base of most grazing food chains”.

Correct Answer: Option D — Ecosystem. Ecosystem is correct because it is a pond, forest or grassland can be studied as an ecosystem. Ecosystem is also specifically associated with biotic and abiotic components interact within it. Two additional identifying facts are that Ecosystem is energy flows while nutrients cycle through the system and Ecosystem is associated with a pond, forest or grassland can be studied as an ecosystem. Why the other options are incorrect: • Option A — Food Chain: Food Chain is interconnected food chains form a food web. It is incorrect here because its separate identifying association is producers form the base of most grazing food chains. • Option B — Biodiversity Hotspot: Biodiversity Hotspot is a hotspot is not simply any place with many species. • Option C — Wetland: Wetland is the Ramsar Convention provides an international wetland framework. It is incorrect here because its separate identifying association is marshes, floodplains, lakeshores and mangrove areas can be wetlands. Exam Takeaway: Connect Ecosystem with “a pond, forest or grassland can be studied as an ecosystem” and “biotic and abiotic components interact within it”.

Correct Answer: Option C — Ecosystem. Ecosystem is correct because it is energy flows while nutrients cycle through the system. Ecosystem is also specifically associated with a functional unit of organisms and their physical environment. Two additional identifying facts are that Ecosystem is energy flows while nutrients cycle through the system and Ecosystem is associated with a pond, forest or grassland can be studied as an ecosystem. Why the other options are incorrect: • Option A — Food Chain: Food Chain is consumers occupy successive trophic levels. It is incorrect here because its separate identifying association is a linear sequence showing transfer of food energy. • Option B — Biodiversity Hotspot: Biodiversity Hotspot is parts of the Himalaya and Western Ghats-Sri Lanka hotspots occur in India. • Option D — Wetland: Wetland is wetlands can store floodwater and support specialized biodiversity.
