Which Environment and Ecology term is correctly identified by “energy flows while nutrients cycle through the system” and “a pond, forest or grassland can be studied as an ecosystem”?

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 pond, forest or grassland can be studied as an ecosystem. 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 interconnected food chains form a food web. • Option B — Biodiversity Hotspot: Biodiversity Hotspot is parts of the Himalaya and Western Ghats-Sri Lanka hotspots occur in India. It is incorrect here because its separate identifying association is a hotspot is not simply any place with many species. • Option D — Wetland: Wetland is wetlands can store floodwater and support specialized biodiversity. It is incorrect here because its separate identifying association is the Ramsar Convention provides an international wetland framework. Exam Takeaway: Connect Ecosystem with “energy flows while nutrients cycle through the system” and “a pond, forest or grassland can be studied as an ecosystem”.
