Question

what are some effects of the tiny beads called microplastics that are a large component of ocean garbage patches?
○ they absorb carbon dioxide.
○ they are often consumed by animals, making animals sick.
○ they clog pipes and drains.
○ they create gyres.

Explanation:

• Option 1: Microplastics do not absorb carbon dioxide; this is incorrect.
• Option 2: Microplastics in ocean garbage patches are often ingested by marine animals. Ingesting microplastics can cause internal injuries, blockages, and the transfer of toxins, making animals sick. This is a known effect.
• Option 3: Clogging pipes and drains is an issue with larger plastic debris or microplastics in terrestrial water systems, not a main effect in ocean garbage patches.
• Option 4: Gyres (ocean currents that trap debris) are what create ocean garbage patches, not microplastics creating gyres.

Answer:

B. They are often consumed by animals, making animals sick.
