Which of the following describes a competitive relationship?

a group of ants attack a large beetle.
a snake and a hawk both try to attack a mouse.
a pack of wolves lives together in a forest ecosystem.
a crocodile bird eats harmful insects off a crocodile's back.

I believe that the answer is a snake and a hawk both try to attack a mouse because both of them are competing to get the same thing that they want so they’re basically fighting over the mouse

A snake and a hawk both try to attack a mouse.
