A bacteria can also go through exponential growth as shown below. The only is how fast the organism can reproduce. Exponential growth only occurs occasionally. In the transition or linear growth phase, the increase will slow down until it reaches zero. This occurs when the environment suddenly changes and only a few individuals survive. Interspecies competition results, where the strong survive. This is when the habitat has reached its carrying capacity. As a population increases, it begins to experience environmental resistance, because and resources are reduced and competition for space and resources increases. If the numbers start to increase above carry capacity, shortage of resources reduces the numbers of offspring produced and the population regulates itself at the carry capacity. If the population is reduced, by heavy predation, for example, the additional resources that then become available lead to an increase in reproductive rate, and the carrying capacity is again reached. In other words, the populations tend to be self-regulating. Take for example, humans over the years.
