Answer:
Competition is the active demand by two or more organisms or kinds of organisms for some environmental resource in short supply. This can happen when two or more organisms need the same resource to survive and thrive, and there is not enough of the resource to go around. In this situation, the organisms may compete with each other for access to the resource, and the one that is able to obtain it will be more likely to survive and reproduce. Competition can be an important factor in shaping the evolution and behavior of organisms, as it drives the selection of traits that are advantageous in acquiring the limited resource.
