Under ideal conditions-sufficient food, water, and space-populations of these species grow expedintional and follow a pattern known as growth. Exponential growth is explosive population growth in which the total number of potentially reproducing organisms with each . However, populations of organisms will increase in size forever. Eventually, on , , and other resources will cause the population to increasing.
When a population arrives at the point where its size , it has reached the of the environment. The carrying capacity is the of individuals a given environment can . Competition for resources among members of a population (specific competition) places limits on population size.
Competition for resources among members of two or more species
(specific competition) also affects population size. In a classic series of experiments in the 1930s, a Russian ecologist, G. F. Gause, formulated his principal of competitive exclusion. This principle states that if two species are for the resource, the species with a more growth rate will the other. In other words, no two species can occupy the same niche.
In competing populations of organisms, that reduce competition are favored through natural selection. Suppose two species (A and B) compete for the same food source. Individuals of species A can also use another food source, which reduces the competition over the food source needed by species B. The individuals of species A that can use another food source survive because they do not have to compete with individuals of species B for that food. In nature, organisms frequently invade unoccupied habitats simply to avoid intense competition. Once the organism is in a new habitat, any variations that allow it to use the available resources will tend to be perpetuated through the population. In this way, the genetic makeup of the population may slowly change, and the species will become adapted to a new niche.
