NEET Biology

Which of the following is the correct statement about "population growth models" — exponential vs logistic growth?

A Exponential growth occurs when resources are unlimited (dN/dt = rN, J-shaped curve); logistic growth occurs when resources are limited and population reaches carrying capacity K (dN/dt = rN(K-N)/K, S-shaped curve)

B Exponential growth occurs when resources are limited; logistic growth occurs when resources are unlimited

C Both exponential and logistic growth produce S-shaped curves

D In logistic growth, the population never reaches a stable size; it continues to grow indefinitely
