Biotic Limiting Factors


This tree is an example of a biotic limiting factor found in our local neighborhood. A biotic limiting factor is a living or once-living feature of an ecosystem that limits a population size. This tree limits the amount of sunlight for the smaller plants lying underneath the tree. The tree limits the population of these smaller plants. Also, this tree limits food for certain animals because of the seeds that grow on it. Therefore, this tree is an example of a biotic limiting factor.
