Solution
The correct option is B T T
Natality is the proportion of births to the total population in a place at a given time, while mortality is the death rate per thousand individuals. Immigration is the movement of individuals into an area and emigration is movement of individuals out of an area. Therefore, natality and immigration will increase population.
When resources are limited, populations exhibit (b) logistic growth. In logistic growth, population expansion decreases as resources become scarce, and it levels off when the carrying capacity of the environment is reached. The logistic growth curve is S-shaped.
