Q. Which is not a natural ecosystem? 

(1) Desert 

(2) Aquarium 

(3) Forest.

Answer:- (2) Aquarium

Out of all the given options, the correct answer is Aquarium. Even though an aquarium is a functioning ecosystem, it is not a natural ecosystem. It is an artificial ecosystem. This is because humans add all the components in the Aquarium like plants, fishes, rocks, water, and others, so it falls in the category of an artificial ecosystem. 

The remaining options, (1) Desert and (3) Forest, are examples of a natural ecosystem. There is no direct involvement of man in their creation. They are formed naturally over time. Their existence is entirely natural and self-dependent by all means.
