Why is the ecological importance of lakes high?

Answer and explanation

Correct answer: They provide habitat to aquatic animals and plants

Direct answer: B. Lakes are ecosystems, not merely collections of water. They provide habitat, food, breeding areas, and shelter for aquatic plants, fish, birds, insects, and other organisms. They also support food chains and biological diversity. To solve the question, connect “ecological importance” with living organisms and their habitats. Option B is correct because it describes the central ecological function of lakes. Option A is wrong because lakes do not exist only to store stones; sediment may occur, but that is not their ecological importance. Option C is scientifically impossible: lakes do not change the Sun’s direction. Option D is also impossible because air does not become solid through the existence of a lake. Memory cue: “Ecology means relationships among living things and their environment; lakes provide that environment.”
