Final answer:
Competition coefficients represent the strength of competition between two species. They are needed when assessing the outcome of competition to determine the competitive advantage of each species. These coefficients can help predict population changes and potential species extinction.
Step-by-step explanation:
Competition coefficients represent the strength of competition between two species. They indicate how much one species affects the other when both species are competing for the same resources. These coefficients are needed when assessing the outcome of competition among two species because they help determine which species will have a competitive advantage.
Competition coefficients can be quantified using different methods, such as the Lotka-Volterra model. This model uses mathematical equations to predict how the population sizes of two competing species will change over time. By analyzing the competition coefficients in the model, scientists can understand the outcome of competition and predict the potential effects on species populations.
For example, if the competition coefficient of species A on species B is high, it means that species A strongly outcompetes species B for resources. This could result in a decline in the population size of species B or even its extinction in the long run. On the other hand, a low competition coefficient indicates a more balanced competition, where both species can coexist without causing significant harm to each other.
