Answer 9

Unlike other cycles of matter compounds, phosphorus cannot be found in air as a gas. This is because at normal temperature and circumstances, it is a solid in the form of red and white phosphorus. It usually cycles through water, soil and sediments. Phosphorus is an essential nutrient for plants and animals in the form of ions. Phosphorus forms parts of important life sustaining molecules but is not very common in the biosphere. Phosphorus does not enter the
atmosphere, remaining mostly on land and in rock and soil minerals.
So, phosphorous cycle is very important to circulate phosphorous in plants as well as whole of the atmosphere coz it occurs as solid and not as gas.

Carbon cycle

It is one of the most important cycles of the earth and allows for the most abundant element,i.e., carbon to be recycled and reused throughout the biosphere and all of its organisms.The global carbon budget is the balance of the exchanges (incomes and losses) of carbon between the carbon reservoirs or between one specific loop (e.g., atmosphere ↔ biosphere) of the carbon cycle. An examination of the carbon budget of a pool or reservoir can provide information about whether the pool or reservoir is functioning as a source or sink for carbon dioxide.

Nitrogen cycle

Earth's atmosphere is approximately 78-80% nitrogen, making it the largest pool of nitrogen. Nitrogen is essential for many biological processes; it is crucial for any life here on Earth. It is in all amino acids, is incorporated into proteins, and is present in the bases that make up nucleic acids, such as DNA and RNA. In plants, much of the nitrogen is used in chlorophyll molecules, which are essential for photosynthesis and further growth.
Although earth’s atmosphere is an abundant source of nitrogen, most is relatively unusable by plants. Processing, or fixation, is necessary to convert gaseous nitrogen into forms usable by living organisms. This makes nitrogen a crucial part of food production. The abundance or scarcity of this "fixed" form of nitrogen, also known as reactive nitrogen, dictates how much food can be grown on a piece of land. Therefore nitrogen cycle is important to make it available to plants which ultimately make food for us.
