Which of the following terms refers to the breeding and living competition between two species for resources?

The term that refers to the breeding and living competition between two species for resources is competition. This biological concept encompasses the struggle between organisms to obtain limited resources such as food, water, and shelter. When two species compete, they may use similar resources in overlapping niches, which can impact their population sizes and overall survival.

Competition is a fundamental interaction in ecological communities and can lead to various outcomes, including the displacement of one species by another, changes in population dynamics, and the evolution of adaptations. This dynamic is crucial for maintaining the balance and diversity within ecosystems, as it influences which species thrive and which may decline or even become extinct under competitive pressures. Understanding competition helps ecologists analyze species interactions and the health of ecosystems.
