A nonnative species of fish is introduced into a lake. Which would most likely prevent this fish from becoming a invasive species?

B

Explanation:

A- The lake ecosystem has no other larger fish

B- The fish shares a niche with another species

C- There are no organisms that would eat this fish

D- The fish can thrive in the temperature of the week

The correct answer would be option B.

One of the factors that promote invasiveness in exotic species is if such species lack natural predators or competitors. In other words, the invasiveness of a nonnative species can be promoted when they occupy a previously unoccupied niche, resulting in a lack of competition. The presence of a competitor will either results in a competitive exclusion that might not favor the newly introduced species or resource partitioning that sort of limits their growth.

Hence, in the case of the nonnative fish introduced into a lake, sharing a niche with another species can prevent it from becoming an invasive species.

c is the correct answer!
