Concepts You Must Know Certain adaptations give some organisms an advantage to survive. The environment "naturally selects" which organisms are best suited (fittest) to survive and reproduce. Those organisms that survive and reproduce pass these favorable traits on to the next generation. This gives their offspring an advantage to survive. Competition for resources (food, water, mates and territory) stimulates the struggle for survival.
