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?

adaptation principle

competitive exclusion principle

niche relationship

predator-prey relationship

Competitive exclusion principle or Gause law

Explanation:

The principle states that two organisms cannot depend on the same limiting resources, and still keep a fairly constant population.

Zebra mussel is an exotic breed not native to the North American continent. it was brought by ships travelling from Europe. The mussels adapted fairly well. The mussel brought about competition between them and the native fishes of the American continent for their food plankton. Competition favored the mussels which resulted in decline of the fishes.  

competitive exclusion principle

Explanation:

An invasive species is the one which is introduced intentionally or accidentally in a new habitat is capable of harming and competing with the native species for resources. The invasive species is capable of limiting the population of the native species.

According to the competitive exclusion principle when two species compete for the same resource then the one which is strong over the other receives the resources and the population of the other decline.

The given situation is an example of competitive exclusion principle. The zebra mussel being an invasive species can compete with the native species of North America. This will result in the decline of the inferior native species.

it is a learned trait

i'm thinking (a) to keep sand in place; ////////////

explanation: a sand fence or sandbreak, like a snow fence, is used to force windblown, drifting sand to accumulate in a desired place. sand fences are employed to control erosion, sand dune stabilization, keep sand off roadways, and to recruit new material in desert areas.
