Question

choose the two best pieces of evidence that support the claim you chose above.
□ zebra mussels take water and food resources from native species in the water ecosystem.
□ zebra mussels take space/shelter resources away from the native species in the water ecosystem.
□ zebra mussels get along with all the creatures, including the herring, in their new environment.
□ zebra mussels travel on boats into a new ecosystem.
□ zebra mussels make the water cloudy.
□ zebra mussels cost a lot of money to remove.

Explanation:

Zebra mussels as invasive species impact native species by competing for resources. Taking water, food, and space/shelter resources from native species are strong evidence of their negative ecological impact. Traveling on boats is about their spread, making water cloudy is a secondary - effect, cost of removal is an economic aspect, and getting along with other creatures is contrary to the idea of their negative impact.

Answer:

Zebra mussels take water and food resources from native species in the water ecosystem.
Zebra mussels take space/shelter resources away from the native species in the water ecosystem.
