how do animals use their sense of smell?

Question

i am doing my science home work i dont know the answer for this question i need help to find the answer.

Answer 1

to find food, attract/find mates, detect danger/predators, identify other animals' territory

-find food e.g. shark smells blood from far away, know that there's weak prey, swims to prey and devours it

- attract/find mates e.g. some female animals have a scent that tells the males they are mature and ready to mate

- detect danger e.g. breeze carries scent of a predator to a deer, deer is alerted, whole herd runs away

- identify territory e.g. wolves mark territory by peeing on trees... ><
