Answer:
Animal behaviour is controlled by the physiological mechanism
Explanation:
There are the known species of fish which communicate with each other through electrical signals or in the form of the electric field. This is known as the electrocommunication and the electroreception.
The communication between two fishes through the electric field is controlled by the physiological mechanism present in the fish and shows that the fish behaviour is controlled by the physiological mechanisms of the fish.
Thus, Animal behaviour is controlled by the physiological mechanism is correct.
