The diagram below shows part of the nitrogen cycle on Earth. The black arrows represent the movement of nitrogen as it is changed. 3Lbxd
The diagram explains the nitrogen cycle on Earth. The black arrows represent the movement of nitrogen and how it changes during the process. Nitrogen gas (N2) in the atmosphere is converted into nitrogen compounds by plants or bacteria in the soil. Animals like the cow shown on the diagram consume the nitrogen compounds, which are contained in the plants. When the animals digest the plant and produce waste, it goes back into the soil. The nitrogen gas is also converted into other nitrogen compounds by bacteria in the soil. Other types of plants and bacteria change these nitrogen compounds from animal waste or other bacteria into nitrogen gas again. The gas goes back into the atmosphere, back where it started from. Nitrogen plays a very important role in our ecosystem. The nitrogen compounds, when absorbed by plants and eaten by animals, provide the building blocks for proteins. These proteins are essential for life.
