Each species in the community maintains its populations by utilizing the opportunities available in its realized niche within the larger habitat. These are needed in order to maintain the colonization of difficult environments and to continue the control of constraining ecological influences. Other important aspects of the niche are environmental tolerance, the organism’s activities, and interactions (competitive and more harmonious) with other organisms. Although niches cannot be seen or felt, ecologists can nevertheless understand their dimensions on the basis of environmental tolerances and opportunities as is discussed below. The influences of these factors are optimized in old-growth tropical rain forests, which maintain a greater diversity of species than any other terrestrial ecosystem.
