Question

question 6 propose ways that plastic pollution might decrease the biodiversity of a marine ecosystem.

Explanation:

Plastic pollution can harm marine life in multiple ways. Marine animals may ingest plastic, causing internal injuries or blocking digestive systems, leading to death. It can also entangle marine organisms, restricting their movement and causing physical harm. Additionally, plastic can alter the habitat by covering the seabed or floating on the surface, disrupting the living - space and food - availability for various species.

Answer:

Plastic pollution can decrease marine ecosystem biodiversity through ingestion by marine animals, entanglement, and habitat alteration.
