Question

Plankton, nekton and benthos are not the components of
A) River ecosystem
B) Oceanic ecosystem
C) Savannah ecosystem
D) Lake ecosystem

Answer 1

Plankton, nekton and benthos are not the components of Savannah ecosystem.

This is because Benthos includes animals that are ecologically linked to the ocean’s floor.

Nekton includes aquatic animals that are able to swim and move independent of any water currents. Thus, Savannah ecosystem is the correct answer.

Answer 2

Answer:

Option C.

Explanation:

Savannah ecosystem is the right answer.

Plankton is the different group of animals that live in large water bodies and are incapable to swim against a flow. The benthos involves animals that are ecologically associated with the floor of the ocean. Nekton encompasses marine or aquatic creatures that are capable to swim and move freely of water flows. However, all these animals in one or another way associated with water and not the component of the Savannah ecosystem.
