What’s extinct?

Extinct means no more are alive. It happens because all of that kind died. You cannot see or hear them now. Dinosaurs are extinct.

Extinct means a kind of animal or plant has no living ones left anywhere. When the last one dies, there are no grown-ups to have babies, so that kind is gone. It is like when every cookie in a jar is gone, and none are left to take out. Dinosaurs and dodo birds are extinct.

Extinct means a whole species is gone. A species is one kind of living thing, like a tiger, oak tree, or dodo bird. When the last one dies, there are no others left to have babies, so that species is extinct. This can happen when homes are destroyed, food runs out, weather changes, or people hunt too many. Fun fact: more than 99 out of 100 kinds of living things that ever lived are extinct now.
