Question

Most animals that live in deep oceanic waters are

• A. primary consumers
• B. detritivores
• C. tertiary consumers
• D. secondary consumers

Answer 1

The correct option is B detritivores

In some animals, food comes from the bodies of dead fish, dead plankton, and even dead whales that rain down from the open ocean waters above. The undissolved material from the decomposition of organic remains is called detritus. It often settles on the ocean bottom. So most animals that live in deep oceanic water are detritivores. They are also called as scavengers. Most of them living in deep ocean include crustaceans and polychaetes.
Thus, the correct answer is option C.
