What is the need for a system of control and coordination in an organism?

Q. 9 :- What is the need for a system of control and coordination in an organism?

 

Answer:-

A living being does not live in isolation. It has to constantly interact with its external environment and has to respond properly for its survival. For example; when a hungry lion spots a deer, the lion has to quickly make a move so that it can have its food. On the other hand, the deer needs to quickly make a move to run for its life.
