FAQ: What Is The Problem Zebra Mussels Cause?

How do zebra mussels affect an ecosystem?

Zebra mussels negatively impact habitats by filtering water, which removes plankton from the water. As a result, the decreased levels of plankton in the water upset the balance of food chains in ecosystems. Also, clearer water as a result of filtering allows sunlight to easily penetrate and warm up the water.

Are there any benefits to zebra mussels?

Mussels are filter feeders, which means they feed by clearing nutrients from the water passing through them. The rate of reproduction and spread of zebra mussels make them efficient cleaners of Great Lakes water, but whether that’s a positive or negative thing depends on who you’re asking.
