What are the processes of the carbon cycle and the nitrogen cycle?

Carbon Cycle:CO2 in the air get taken in by plants through photosynthesis. Carbon is in plant. Animals eat the plant. Carbon is in animal. Animal droppings contain carbon. Decomposersbreak down droppings into CO2. CO2 returns to air.OrPlants and animals die. Decomposers break down remains into CO2.Alternative ways for carbon to enter the cycle include combustion and respiration of animals and plants.Nitrogen Cycle:Nitrogen in air gets combined with oxygen with lightning. Nitrates are in soil. Plants take Nitrogen as Protein. Nitrogen in plant as Protein. Animals eat plant. Proteins in Animal. Plants and Animals die. Decomposers break down Proteins and Nitrogen gets released into the air again.
