what happens when one organism utilizes a resource that another organism needs in an ecosystem?
it increases the population growth of both organisms.
it creates competition between the organisms.
it results in increased cooperation between the organisms.

Explanation:

In an ecosystem, when one organism uses a resource that another needs, it leads to competition as they are vying for the same limited resource. Population growth of both doesn't increase as resources are limited. Cooperation is not the result when resources are in short - supply and being fought over.

Answer:

It creates competition between the organisms.
