An example of a terrestrial ecosystem is one that contains sand and water, where fish feed on plankton, and the plankton in turn feed on algae.

Is the above example true or false, and why?

False; an ecosystem with sand, water, fish, plankton, and algae would be aquatic, not terrestrial.

True; an ecosystem with sand, water, fish, plankton, and algae is an example of a terrestrial ecosystem.

False; this example is missing whales as another organism in the ecosystem.

True; these organisms and factors, as well as whales, are a part of a terrestrial ecosystem.

I will give the first person brainliest

Option (1)

Explanation:

A terrestrial ecosystem is usually referred to as the ecosystem comprising all the trees and plants such as the grasslands, deciduous as well as the rainforest areas.

On the other hand, an aquatic ecosystem refers to the water bodies where there occur different species of living organisms and that interacts with the components of its ecosystem.

The above-given statement is false. It is because the major components are given here namely the water, fishes, algae, and planktons represents an aquatic ecosystem. The sand here is an abiotic component that used to be present in the aquatic ecosystem also. Here, the fishes feed on the planktons and these planktons also feed on the algae.

Thus, the correct answer is option (1).
