It is characterized as interaction because, as the organisms compete, they are involved in one on one battle of acquiring the resource by overpowering the other. The struggle that occurs between organisms for food and water and energy when resources are limited is called competition. Intraspecific Associations: In intraspecific association individuals are quite similar in their resource require­ments. The organism in the photo is a daphnia, or water flea. Intraspecific competition is a major force in ecology. When resources are limited, populations exhibit logistic growth. When resources are scarce, however, organisms must compete with other organisms to obtain them. When resources are scarce, power-law distributions of flight times with scaling exponents μ ≈ 2 give rise to the so-called Lévy walks. In economics, scarcity refers to the gap between insufficient resources and the theoretical needs people have for these resources. ecology, nonliving.
