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

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.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
