Answer 1

If phytoplanktons are destroyed in the sea then it will affect the food chain.

Phytoplankton is an important part of the food change and its extinction will bring a barrier in the food chain which will in turn have drastic effects.

Thus, being an integral part of the food chain, phytoplankton is necessary in keeping it working.
