Question

How does the environment select organisms

Answer 1

Environment selects organisms by only allowing organisms of certain trait or abilities to survive in the environment. For example, a polar bear cannot survive in the desert because it's thick fur is adapted to colder environment. The idea of the survival of the fittest is involved in the process

Answer 2

The process in which the environment selects organisms that will survive is called natural selection. It starts with overproduction; when an organism produces more offpsrings than can survive. The second is variation. Because there are so many offsprings, there will be variations.
