All living "Organic" things or life forms will mutate as a process of natural selection. This ensures that the strongest species survives. Without mutations, organisms would not evolve or improve their success to survive!
Causes of variation is random mutation. Random mutations constantly occur in the genomes of organisms; these mutations create genetic variation. If all living things were same, we will all use up one type of food as our nutrient source and eventually we will run out of food to consume.. making less likely for us to survive..
Humans and all other living organisms called biotic factors effect environment .
Mutations happen in ALL living things (and also in viruses)!!!!!!

Many, if not most, mutations are neutral, meaning that they have little or no effect on the expression of genes or the function of the proteins for which they code.

Most mutations that occur have a neutral effect, or none at all, so they would not affect evolution. Organisms with mutations that cause detrimental impact typically will not survive; therefore, they will not reproduce, and the mutation will not be passed on, so the species will not be affected overall. Beneficial mutations are typically the only mutations that will affect an organism's posterity and the evolution of its species, but good mutations are very rare. This is why most mutations have little effect on the evolution of a species.
nitrogen has no effect to life

The destruction of natural resources in living organisms can have a negative effect on the ecosystem. destroying the environment where an organism lives can reduce the number of organisms in the area.

Humans and all other living organisms called biotic factors effect environment .
The effects of pollution on living organisms include mutations, exposure to carcinogens, and introduction of unnatural compounds and elements into their habitats. Effects on the non-living environment include changes to Earth's chemistry and atmosphere.
Usually mutations have deleterious effects to the organism, but occasionally there are beneficial mutations. Such mutations drive evolution.
