Answer:

Water pollution affects aquatic life by killing them and by disrupting the food chain.

Explanation:

When polluting chemicals, like sewage, are dumped into the oceans, animals that depend on the ocean to survive, such as crabs and fish, die off. This is because the animals could be infected by diseases from the sewage or be harmed by trash that is thrown in the ocean. Also, pollutants like lead and cadmium are consumed by small animals. Since these small animals die off, the small animals' predators have no food, so they die off. This continues up the food chain and can destroy entire ecosystems.
