How does the environment select organisms?
Answers
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. The third step is selection. When the actual "selection" occurs. If the variation is helpful to survive, then it gets passed down. This is the fourth step: adaptation when it is passed down to offsprings for generations.
