Question

Zebra mussels are originally native to Russia. In the mid-1980's, zebra mussels were introduced into the Great Lake region of the United States where they rapidly reproduced; females can produce up to one million eggs per year. All BUT one situation would be a problem caused by the introduction of this invasive species. That is A) damage to boats, harbors, and docks. B) helping other species of mussels thrive and grow in size. C) damage to water treatment plants by clogging up the intakes. D) out competing native species for food, leading to a decrease in their population.

Answer 1

B is the correct answer

Answer 2

The correct answers are option C- damage water treatment plants by clogging up the intakes and option D- out competing native species for food, leading to a decrease in their population.

Each zebra mussel can filter up to liter water per day to feed on plankton. Sea plankton are the source of food for zebra mussels and they eat a lot of plankton which makes it harder for other sea animals to find food for themselves.

Second problem zebra mussel caused was clogging the water pipes by growing and dividing inside them which disrupts water flow.
