Question

A pattern of idealized population growth, restricted by limiting factors is shown by

• A. Logistic growth model
• B. Carrying capacity model
• C. Dispersion model
• D. Habitat cap model
• E. Exponential growth model

Answer 1

Answer: (A)

Logistic growth model

Population growth rate measures the number of individuals in a population (N) over time (t). When the conditions are ideal, the type of growth is known as exponential form of growth which is expressed by the equation, (dN)/(dt)= rN. When the limiting factors is restricted, the growth pattern is known as logistic growth model. This model is described by the differential equation (dN)/(dt)= rN(K-N)/K, where K is the carrying capacity and r is the maximum per capita growth.

Therefore, the correct answer is option A.
