Mutations lead to genetic variation by producing random changes in an organism's genetic code.

This causes a different protein to be produced, or none at all.

Usually has a negative effect, due to an important protein, e.g. an enzyme, not being produced, so the organism cannot do a certain thing (e.g. digest fats), occasionally makes an organism better able to survive (positive effect). This means that it is more likely to survive and pass the mutated (beneficial) gene on to it's offspring.

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

Explanation:

Atmosphere would be most immediately affected by a decrease in sunlight because sunlight is responsible for the photosynthesis in plants. if sunlight decreases, the photosynthesis reaction is also decreases in plants and less carbondioxide gas is used by the plant from atmosphere for making their food so we can say that atmosphere is greatly affected by the decrease in sunlight.
