Question

A population grows exponentially when___________.

a. the death rate equals
b. the birth rate and immigration is equal to emigration emigration exceeds immigration and the birth rate equals
c. the death rate the birth rate exceeds
d. the death rate and immigration exceeds emigration
e. the carrying capacity is exceeded

Answer 1

birth rate exceeds death rate and immigration exceeds emigration.

Step-by-step explanation:

Exponential growth is the increase in population of a species per unit area in a habitat in a given time when the resources available are unlimited.

Change in Population Size = (Births + Immigration) - (Deaths + Emigration)

From the equation above, for a positive change in population size, the sum of the births and immigration must be greater than the sum of the deaths and emigration.

Answer 2

The birth rate exceeds the death rate and immigration exceeds emigration

Explanation:

The exponential population growth is not usual in nature, this phenomenon occurs when there are no natural factors (for example, competing resources, depredators, etc) capable of limiting population growth
