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? A) adaptation principle b) competitive exclusion principle c) niche relationship d) predator-prey relationship

The right answer is b) competitive exclusion principle (principle of Gause)

In fundamental ecology, and more specifically in population biology, the principle of Gause (or principle of mutual exclusion, or principle of competitive exclusion) is a principle of population dynamics stipulating that two populations can not subsist on the same ecological niche.
