Question

What are endangered animals?

Answer 1

Species that are near extinction

Explanation:

The reason is often that humans have hunted them for different reasons until there are almost none left.

Tigers are one example.

All species are necessary for the ecosystem to function.
For example... If all cats die, there will be too many mice and rats, meaning more disease.
If you remove any species, there will be a hole that would need filling or everything could collapse.

Species are dependent on each other
