Water and minerals needed by all organisms on earth pass back and forth between the biotic and abiotic portions of the environment in a process called

This is known as the a biogeochemical cycle. This is a very broad term given for any substance that cycles through biotic (biological) and abiotic compartments on Earth. These cycles are known for carbon, oxygen, nitrogen, phosphorus, sulfur, and water. The water or hydrological cycle is arguably the most well-known cycle. Water cycles between water vapor in the clouds, rainfall, rivers lakes and ocean as well as ground water and back into water vapour. During the terrestrial phase, water also passes through plants and animals.

Amutation is basically the change in the gene, caused by alteration of single based units in the dna, or the genes or chromosomes were rearranged in the dna
