Stop trying to act smart no one cares just get to the point

The proteins are composed of amino acids as their monomeric unit. There are 20 different types of amino acids which forms the different types of proteins.

how a decreased number of locusts would affect other organisms.

Explanation:

When engaging in any action aimed at destroying large numbers of an organism as is the case here, there is always a need to check what impact it might have on the ecosystem at large.

This is why it is very important that the effect of a decreased number of locusts on other organisms is evaluated before such drastic action is taken. If it would lead to a situation where the ecosystem is destabilized, the consequences would be far reaching and very damaging.
