There are three importation cycles that the environment. The three cycles are carbon, phosphorus and nitrogen cycles. These cycles are part of photosynthesis. These are a chain that keeps everything going in the word. These cycles keep animal alive and plants and people breathing.
Carbon cycle is an Importation one of the cycle on earth. You get carbon atoms from co2 then become carbon atoms of the organic molecules are making up the plant bodies. Then the carbon atoms are eaten my animals. This cycle comes from fossil fuel also this create CO2. The carbon atoms cycle from atmosphere through one or more living things and back to the atmosphere about every six years. Human benefit as well in this cycle we get fossil from the ground witch we can turn into other thing also.
Nitrogen cycle is a cycle made up of the carbon and phosphorus cycles. Nitrogen has a gas phase. Nitrogen is otherwise unique. Unlike the other cycle’s bacteria in the soils, water and sediments perform many of the steps of the nitrogen cycle. Human benefit with this cycle also as well it helps crops that are on the farm. This cycle is a big part of the ecosystem.
Phosphorus Cycle is a similar to the other cycles of other mineral nutrients. They focus on this because its shortage tends to be a limiting factor in a number of the ecosystem and its excess can stimulate unwanted algal growth in freshwater system. This is a soil cycle mostly. Help the earth in many ways. We get help with the animals in this cycle.
These cycles are a part of photosynthesis. This is how we her rain and water to wash are self with. These are what give us air and gas for are cars all that stuff comes from the earth. This help are food supplies are food and help are animals. The animals eat the plants and other stuff. The crop that we grow from the grown the cycle help with the soil and the neutrons it need.
