Nitrogen Cycle

How the Nitrogen Cycle functions on Earth

Nitrogen Cycle description

Nitrogen is found naturally in the atmosphere. When a lightning bolt comes along and strikes something, it breaks down bacteria and settles in the soil. The plants absorb nitrogen and animals that feed off plants consume nitrogen through eating said plants. When an animal either defecates or dies the Nitrogen is deposited into the soil and becomes ammonia (NH3). While in the soil it undergoes Nitrification, and becomes Nitrite. It undergoes the process again to become Nitrate. It's an extremely important element to all life forms on Earth.

Imagining life without Nitrogen

Since nitrogen is so important to plants, providing a base for amino acids, proteins, and nucleic acids, plants themselves would not be able to live. Without plants the entire world would be uninhabitable because they make oxygen for humans to breathe in. So without Nitrogen we would not be able to live.
