Question

Which is the simplest aquatic ecosystem?

(a) Pond

(b) Stream

(c) Lake

(d) Marine

The question was posed to me during an interview.

My enquiry is from Aquatic Ecosystems in section Ecosystems of Energy Management

Answer 1

Correct answer is (a) Pond

To explain I would say: Pond is the simplest aquatic ecosystems. Most ponds become dry after the rain over and are covered by terrestrial plants for the rest of the year. When the ponds fills in the monsoon season, a large number of food chains formed in the pond ecosystems.
