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.

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

Explanation:

The competitive relation for a species exist in biological community when the two different species in the same ecosystem compete for the food, water or to mate with each the for territory and thereby exists in a competitive environment where the survival of the fittest is essential, and chances of rivalry also occurs between the species as due to the inter-species competition.

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
