Interactions between organisms and their environment impact the organism’s overall population. zebra mussels are not native north america; they were brought here by ships travelling from europe. they reproduce quickly and filter out plankton from the water reducing food for native fish. native fish populations have started to decline. which concept shows the relationship between zebra mussels and native fish?

The right answer is competitive exclusion principle.

The concept of competitive exclusion states that populations of two species with identical ecological requirements, that is, exploiting a single limiting resource, can not coexist indefinitely in a stable and homogeneous environment, the most competitive of the two species ending more or less long term by eliminating the other.

This principle amounts to saying that two species can not share the same ecological niche (set of ecological requirements).
