Answer 1

Answer:

Exponential growth is continuous population growth in an environment where resources are unlimited; it is density-independent growth.

dN/dt = rN where dN/dt = change in population size; r = instrinsic rate of increase (= per capita rate of increase and equals birth rate minus death rate); N = population size.

Nt = No e^rt where Nt = population size at time t; No = original population size, r = intrinsic rate of increase and t = time

Logistic growth is continuous population growth in an environment where resources are limited; it is density-dependent growth. Logistic growth is characterized by a sigmoidal or S-shaped growth curve.

dN/dt = rN [K - N/K] where dN/dt = change in population size; r = intrinsic rate of increase; N = population size; K = carrying capacity.
