In any habitat, food is limited and the types of foods available may vary. Animals that are better adapted to take advantage of available foods will fare better than those who are less well adapted, and thus live to pass on their genes to the next generation. While this concept seems rather obvious, it is essential that each student fully grasp its significance. Understanding the idea of adaptive advantage opens the door to understanding populations in ecosystems as well as the process of evolution.
