Competitive Exclusion Example: How Species Compete for Resources

Words: 823 Pages: 3 3505

Species often depend on the same limited resources, including food, water, shelter, and space. When two species rely on the same resource in the same way, competition can become intense. A clear competitive exclusion example occurs when two species occupy almost identical ecological niches and one uses the available resources more efficiently. Over time, the stronger competitor may force the other species to leave, change its behavior, or disappear from that area. This idea is known as the competitive exclusion […]
