Question

Marine animals are harmed by toxic chemicals and by _____.

Answer 1

They are also harmed by oil. This usually happens when it is runoff from the land. They are also hurt by debris like plastics. These can entangle animals. These can also be eaten by marine animals, which will also hurt them.

Answer 2

Answer

D. Discarded plastics nets and fishing lines

Explanation

Plastic nets and fishing lines discarded into water bodies are examples of solid waste pollution on water bodies. These items potentially lower the quality of water thus putting the life of marine animals at risk. Other  factors that can harm marine life are oil spillage, runoffs containing farm fertilizers which cause eutrophication, and  untreated sewage released to water bodies.
