The number of births per 1,000 individuals for a certain time period is called the ________________.

• estimate

• death rate

• birth rate

• exponential growth

The number of deaths per 1,000 individuals for a certain time period is called ____________.

• estimate

• exponential growth

This is a growth pattern in which individuals in a population reproduce at a constant rate, so that the larger a population gets, the faster it grows.

• birth rate

• death rate

• exponential growth

• logistical growth

• constraint

• pollution

• affected quality

• waste management
