The life cycles are the function a living being have to do.



The life cycle of a living being is to: be born, to grow, to reproduce and to die.



In some life cycles there are metamorphosis, that is the case of : the frogs, the buterflies and many other insects.The metamorphosis are part of the growing process of the living being.



when the living being is in the part of the cycle when it have to reproduce, the kind of reproduction are diferent depending of the leaving being.The living beings that are less evolved use the asexsual reproduction, in this kind of reproduction the leaving being make an exact copy with the same dna and with out join with another living being.



The most evolved living beings use de sexual reproduction, it this one to living beings of different sex join and the son is a mix of the dna of the to parents.
