Cycles of life.



I learn that there are three cycles of life that are:water cycle,carbon cycle and nitrogen cycle.In the water cycle it goes first from the evaporation that changes liquid to gas. Condensation is the change from gas to liquid.Next come the freezing that changes liquid to solid.And the melting that is from solid to liquid.Then everything start again.Other cycle of life is the carbon cycle that is when we breath and when we use a lot of cars we give carbon to the plants and the plant give us CO2 that is oxygen.Thats why when we burn a tree,itbecomes carbon.The other cycle of life is nitrogen cycle that is that the air have nitrogen and the decompossers are eaten by fungi and bacteria and ammonia and then it goes from the nitrites and to the air again.
