An animal’s fundamental niche includes the full range of conditions and resources in which it could survive if it were free from interference from other species. Its realized niche is...

Second, the greater the diversity of niches within an ecosystem, the greater the variety of energy flows and thus the more stable the ecosystem. Third, the introduction of exotic species into an ecosystem, either deliberately or by accident, can create problems because they sometimes compete with native species for niches and food supplies, but in the absence of predation or other...
