one cause of extinctions.
6. Cutting habitats up into small pieces interferes with an animal’s ability to
get to food and water.

7. Introduction of plants or animals that are not native to an area can crowd
out the native plants and animals.
8. Pollution by oil, chemicals, trash and other contaminants can harm the
environment and all the animals in it.

became extinct in this way, but conservation efforts and strict rules about
hunting saved it from extinction.
10.Endangered means nearly all the members of a living thing have died and
there is chance that animal might become extinct.
11.Threatened animals are ones whose numbers are dwindling and might
become endangered if not protected.

refuges, by obeying hunting and fishing laws, and by not releasing animals
into the wild that do not belong there.
