Question

Because of the scarcity of food in the deep-sea environment, many organisms rely on _________ as their principal source of food.

Answer 1

Answer:

Detritus

Explanation:

    Common sense suggests that animals ingest plastic because it is present in the oceans and animals cannot distinguish it from real food (for some animals, such as anchovies, plastic can smell like food). But that does not explain why only certain types of whales - deep-toothed whales such as sperm whales, pilot whales and beaked whales - appear dead on the beaches with plastic in its stomach.

    These species hunt in the depths of the ocean, sometimes more than 500 meters below the surface, in total darkness. They use echolocation to look for food - usually squid. Toothed whales may think plastic waste is food because of its appearance.

Answer 2

The correct answer is detritus
