Degine adaptation. what happenes to the animals which canont adap in the environment​

They will not be able to survive as well as others, like for example: your an animal that likes clean air, or can only survive in clean air, and u go to a place with polluted air, you will not be able to survive if you dont adapt to the polluted air enviroment. That can lead to endangerment and even extinction.

Hope this helps.
