Answer 1

Answer:

1. adaption

Explanation:

Salmon have special adaptation behavior that allows them to live in both freshwater and saline water during their lives.

Salmons are born in freshwater where they spend few months and then move to saline water. For laying eggs, they again move to freshwater because eggs are unable to survive in saline water due to a process known as osmoregulation.

Moving from freshwater to ocean water, salmon adapt according to the environment for their survival.

Hence, the correct answer is "1. adaption"
