Question

Name an organism found as secondary carnivore in an aquatic ecosystem.

Answer 1

In an aquatic ecosystem, food chain can be drawn as follows

Producer (Phytoplankton) → Primary consumer (Zooplankton) → Secondary consumer (small fish and water beetle)(1^st to carnivore) → Tertiary consumer (Iind carnivore like large fish, water birds like fowl and duck).

So, the large fish and water birds like ducks and waterfowl which are the tertiary consumers in an aquatic ecosystem occupy a position of the secondary carnivore.
