Respuesta :
American crocodile population will decrease.
Explanation:
In the food chain mangrove water snake is being consumed by American crocodile. The increase in the size of mangrove water snake would make it difficult for American crocodile to attack its prey.
The large size of the tertiary consumer would compete with the quaternary consumer in the food chain.
The quaternary consumer will find difficulty in having food and ultimately die thus decreasing the number of American crocodiles.
