How do animals obtain their nitrogenrequirements?

Animals get the nitrogen they need by eating plants or other animals that contain nitrogen. When organisms die, their bodies decompose bringing the nitrogen into soil on land or into ocean water. Bacteria alter the nitrogen into a form that plants are able to use.

How do animals get nitrogen * Your answer?

The plant absorbs nitrogen from soil through the roots. Animals get their nitrogen by consuming plants and other animals.

Do animals obtain usable nitrogen?

Animals are able to obtain nitrogen through eating plants and animals. Nitrogen goes back into the soil through animal wastes and decomposing animals and plants. Plants have much harder time obtaining nitrogen as they can only absorb nitrogen when it is mixed with oxygen or hydrogen.

What form of nitrogen do animals need?

Nitrates can be used by plants and animals that consume the plants. Some bacteria in the soil can turn ammonia into nitrites. Although nitrite is not usable by plants and animals directly, other bacteria can change nitrites into nitrates—a form that is usable by plants and animals.

How is nitrogen metabolism in animals?

Nitrogen metabolism is often viewed only as a set of pathways for forming nitrogenous endproducts from protein degradation. ... Ammoniotelic animals form ammonia as their main nitrogen endproduct. Because ammonia is so highly diffusible and rapidly excreted its contribution as an osmolyte is not significant.

How do plants get their nitrogen?

Plants cannot themselves obtain their nitrogen from the air but rely mainly on the supply of combined nitrogen in the form of ammonia, or nitrates, resulting from nitrogen fixation by free-living bacteria in the soil or bacteria living symbiotically in nodules on the roots of legumes.
