Answer :
Answer:
B. Nitrogen Cycle
Explanation:
Without Nitrogen , plants become yellowed which means they will produce smaller fruits and flowers.
Farmers add fertilizers containing nitrogen to their crops, to increase crop growth but without nitrogen fertilizers, we would lose up to one third of the crops we rely on for food and other types of agriculture.
Carbon is found in all organic macromolecules and is also a key component of fossil fuels. See the carbon cycle article for more info.
Nitrogen is needed for our D, N, A, R, N, A, and proteins and is critical to human agriculture. See the nitrogen cycle article for more info.
Phosphorus is a key component of D, N, A, R, N, A, and is one of the main ingredients—along with nitrogen—in artificial fertilizers used in agriculture. See phosphorus cycle article for more info.
Sulfur is key to protein structure and is released to the atmosphere by the burning of fossil fuels.
These cycles don't happen in isolation, and the water cycle is a particularly important driver of other biogeochemical cycles. For example, the movement of water is critical for the leaching of nitrogen and phosphate into rivers, lakes, and oceans.
