Because atmospheric nitrogen can't be used by plants and animals. Only by soil. nitrification it is the conversion of ammonia first into nitrites then into nitrates by nitrifying bacteria and denitrification is the conversion of nitrites and nitrates into free nitrogen.

<h3>What is vegetarian diet?</h3>
- Diets based on plants typically use a lot less energy than diets based on livestock.
- This is mostly a result of the need to feed livestock animals a lot of vegetation.
- For instance, when a person consumes a plant, around 20% of the plant's energy is transferred to the person for use as fuel or to repair bodily tissue.
- The same grains and soybeans that are farmed for animal feed are also used to feed humans.
- Feeding meat eaters requires more space than feeding vegetarians does.
- Additionally, a pound of beef requires 5 to 15 pounds of grain to be produced.
- Vegetarians have more energy available since they are one trophic level lower than the other parents.
