Question

The zebra mussel is a shellfish native to Europe. During the early 1900's, it was accidentally brought to the United States in the ballast of a ship traveling to the Great Lakes. It has no predators in the Great Lakes. What impact are zebra mussels likely to have on food chains in the Great lakes?

Answer 1

Answer:

They may make food unavailable to other organisms that feed on the same things as themselves.

Explanation:

The muslin zebra is considered an exotic species in the American territory, since it was brought to the USA by the Europeans. The problem with exotic species is that there are no predators to control the growth of their population. As a result, this species will compete with native species for food. As there are no natural predators, the population of the exotic species will grow in an uncontrolled manner, exercising unfair competition for food. As a result, the exotic species can deplete the food of other species, leaving them with nothing to eat, which may cause the species to exist.

Answer 2

They will compete with other shellfish and clams and hurt their populations.
