Question

Nitrogen biogeochemistry. Why is nitrogen ( N ) important for plants and animals? In the biogeochemical cycle of N, wow do agricultural soils receive and store N ? What three pathways cause the loss of N in agricultural soils? Questions ( 8 points each) Please address the following prompts in less than 300 words each.

Answer 1

Step-by-step explanation:

1. This is important because nitrogen helps build the proteins in all biotic things. When building protein, it makes the monomers, amino acids. It helps with other monomers for genetic materials. Also, nitrogen makes up some % of the air for biotic's to breathe. Though some biotic's cannot get nitrogen without going through the transformation. N2 would be transformed to nitrogen fixation.

2. Soils receive and store nitrogen by going through the nitrogen cycle. The nitrogen cycle is nitrogen fixation, nitrification, ammonification, and denitrification.

3. At least three ways nitrogen can get losted in soils are soil erosion, denitrification, and volatilisation.
