Lakes are part of which type of ecosystem?

Answer and explanation

Correct answer: Aquatic ecosystem

The direct answer is A, aquatic ecosystem. An ecosystem is a living community together with its non-living surroundings. In a lake, water is the main environment, and organisms such as fish, insects, algae, aquatic plants, birds and microorganisms interact with factors such as water, light, oxygen and nutrients. Therefore a lake is an aquatic ecosystem. Option A is correct. Option B, only desert ecosystem, is wrong because a desert is a dry land environment, while a lake is water-based. Option C, only mountain rock system, is wrong because rocks may be part of a habitat but do not define a lake ecosystem. Option D, only air system, is wrong because air alone is not the complete environment of lake organisms. The word “aquatic” means related to water. Memory cue: aqua means water, so lake, pond, river and sea ecosystems are aquatic ecosystems.
