Why is recycling nitrogen important?

Nitrogen is one of five elements (the others are carbon, hydrogen, oxygen, and phosphorus) that make life possible. It is essential for the creation of DNA, amino acids and proteins. … When organisms die, bacteria recycle the nitrogen in them, and it eventually returns to the atmosphere to complete the nitrogen cycle.

How nutrients are recycled on Earth?

Nutrients in the soil are taken up by plants, which are consumed by humans or animals, and excreted again by them — or they are released back into the environment when organisms die (e.g. plants lose their leaves). … Essentially, all nutrients that plants and also human beings require to survive are cycled in this way.
