When large numbers of organisms share limited space and resources, the result is competition. Competition occurs when organisms struggle to obtain resources like food, water, and shelter in an environment where there are limited supplies. The organisms that are better adapted to the environment and able to obtain the resources they need are more likely to survive and reproduce, while those that are not as well adapted may die off or become extinct. This process of natural selection helps to ensure that the fittest organisms are able to survive and pass on their genes to future generations.
