A biotic factor that affects the distribution and abundance of organisms in a terrestrial habitat is competition. Competition occurs when two or more individuals or populations try to use the same limited resource, such as food, water, or shelter. In a given habitat, there may be multiple species competing for resources, and the outcome of this competition can have a significant impact on the distribution and abundance of each species. For example, if two species have overlapping ranges and compete for the same food source, one species may outcompete the other and drive it to a different location or even cause it to become extinct in the area. Competition can also occur within a species, such as when members of the same population compete for limited resources. This can lead to changes in the distribution and abundance of individuals within that population, as those that are better suited to acquiring the limited resources are more likely to survive and reproduce. While temperature, pH, and light can also affect the distribution and abundance of organisms in a terrestrial habitat, these are considered abiotic factors, as they are non-living components of the environment.
