During exponential growth, a population always

(A) has a constant per capita population growth rate.

(B) quickly reaches its carrying capacity.

(C) cycles through time.

(D) loses some individuals to emigration.

A scientific study that focuses on the size, distribution, and change of a group of individuals (human population) based on their birth and death rate is called population study.

The exponential growth in a logistic curve gives the information about no effect of population size on the growth of each individual in a population.

Thus, the constant per-capita growth rate leads to population size being increased exponentially.

Therefore, the given statement is true.

In a growth curve, when environmental conditions like food, water, and habitat support the species within average population size, it is called carrying capacity.

Thus, the population growth as an exponential function does not frequently approach the carrying capacity.

Therefore, the given statement is false.

In the logistic curve, the population cycling shows the population change, such as increase and decrease over a specified time.

Thus, the per-capita increases, but there will not be population cycling.

Therefore, the given statement is false.

In ecology, the pattern of behavior in which a biological species leaves a habitat permanently and then moves into another is called emigration.

Thus, no loss due to population emigration is taken into the exponential growth.

Therefore, the given statement is false.
