Variations in species help them to adapt themselves to that particular environment and give them a chance of survival. For example, thermophilic bacteria are variants that are resistant to extreme temperature. They have a chance of survival in high temperate zones while others die.

By definition, the phenotype is the actual physical manifestation of an organism's genotype, so the way an organism looks or behaves is what is being selected on. For example, if ladybugs have red (R) shells or yellow (r) shells and ladybug-eating birds only eat the ones with red shells, any red-shelled ladybugs will be selected against based only on their phenotype. The birds do not know whether each bug is RR, Rr, of rr, so phenotype, not genotype, is what is affected by natural selection.
Natural selection is the process in nature by which organisms better adapted to their environment tend to survive and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes eaten by snakes and birds.
