Nitrogen Cycle: The biogeochemical cycle wherein nitrogen is converted into various forms as it circulates through the atmosphere and various ecosystems is named as the nitrogen cycle.

Phosphorous Cycle: The biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere is known as the phosphorus cycle.

Decomposers: The organisms (bacteria, fungi, etc.) that break down the dead and waste organic matter into simpler compounds and use them as food are known as decomposers. The process is known as decomposition.
