When two animals live in the same area and depend on the same organism for food, they are considered to be in competition for that food source.

Here's why:

* Competition is a relationship where two or more organisms strive for the same limited resource, such as food, water, space, or mates.

* If both animals rely on the same organism for food, they are competing for that limited resource.

This competition can be:

* Interspecific: Between different species. For example, lions and hyenas competing for zebras.

* Intraspecific: Within the same species. For example, two lions competing for the same zebra carcass.
