Question

why do some multicellular organisms do chemical communication instead of nervous communication​

Answer 1

Answer:

The role of the nervous system is to send nerve impulses or electrical messages that keeps the multicellular organism aware of its surrounding. This alone cannot subsitute for the need of other means of communication between organs of the multicellular organism. The organs in the multicellular organism also require nutritional nourishment and oxygen supply which are brought about by vascular communication between them. Chemical communication(hormonal communication) between the organs is also important because it produces a longer lasting effect than nervous communication. This brings about long lasting adaptations. The organs of the organism cannot survive on nervous communication alone.

Explanation:

Answer 2

This communication has long lasting effects.

Explanation:

• The communication in the body is important for the proper maintenance  of homeostasis of the organisms.
• The two main system used for the communication are hormonal system used chemical substances and nervous system use electrical signals for the communication.
• Nervous system is quite faster than the chemical communication and its effects remains for short period of time.
• The chemical system activates against the specific chemicals. This system is quite slow and has long lasting effects in the organisms body.
