Answer:
Microbes are vital to control biogeochemical cycling of the elements essential for life.
Explanation:
Microbes are vital to control biogeochemical cycling of the elements essential for life. In a biogeochemical cycle, nutrients move through the ecosystem, allowing many forms of matter being passed from one organism in one part of the biosphere, to another organism in another part of the biosphere (microorganisms can circulate through biotic or abiotic ecosystems), in this way, ensuring the supply of essential nutrients for plant crop and growth, the degradation of organic matter, the maintenance of soil quality/structure and the carbon losses to the atmosphere. In conclusion, without microbiological activity, nutrients cycling and other functions in the ecosystem would be impossible.
Answer:
A mutation happens by chance it cause by the rna polymerase copying the wrong piece of code from your dna leading the wrong protein to be made.
This could either be beneficial or not as it causes variation in a species helping them evolve becuase of survival of the fittest or threatening extinct of the entire specise if their environment has changed as it could threat their survival therefore having variation with in species could help increase their survival rate
