Logistic Population Growth Equation
-
The equation of Verhulst-Pearl logistic growth is $\frac{dN}{dt}=rN\left[\frac{K-N}{K}\right]$. From this equation, K indicates:In the logistic growth equation $\frac{dN}{dt} = rN\left[\frac{K-N}{K}\right]$, N is population density, r is the intrinsic rate of natural increase and K is the carrying capacity. Carrying capacity is the maximum population size that the environment can support with its available resources.
Gause's Competitive Exclusion Principle
-
Given below are two statements: Statement I: Gause's competitive exclusive principle states that two closely related species competing for different resources cannot exist indefinitely. Statement II: According to Gause's principle, during competition, the inferior will be eliminated. This may be true if resources are limiting. In the light of the above statements, choose the most appropriate answer from the options given below:Gause's competitive exclusion principle states that two closely related species competing for the same resources cannot co-exist indefinitely. During competition, the competitively inferior species will be eliminated; this may be true if resources are limiting. As per the solution in the source, both statements are treated as true.
