Introduction Competition and predation can impact the community structure in various different ways. Competition can affect the population size, for example, by increasing or decreasing a population depending on the resource availability. If there is an unlimited amount of resources the population will grow exponentially. However, if there is a limited amount of resource, the population will reach a highest population size, or carrying capacity (Jensen 3). Species composition will also be affected by competition and predation depending on which species is the predator or the competitively superior. Competition and predation can affect the growth rates, as well. As competition and predation increases, the growth rates of the prey or the competitively inferior species’ rate of growth will decrease in population and the predator or the competitively superior species’ rate of growth will increase. This will flip once there aren’t any more prey or resources left for the predators and the competitively inferior. We will build a small ecosystem, each labeled Treatment 1, Treatment 2, and Treatment
