Question 1

What is population growth?

Accepted Answer

The rate at which a population can grow, given environmental limitations such as the available resources and space

Question 2

What is exponential growth?

Accepted Answer

When populations grow at a constant rate (r), making the population grow faster and faster as it gets larger

(bacteria in a petri dish)

Question 3

Does exponential growth occur in nature?

Accepted Answer

Yes, but only in the short-term

Resource availability will make the growth logistic in the long-term

Question 4

What is logistic growth?

Accepted Answer

When a population's growth rate (r) decreases as it approaches carrying capacity

Question 5

What is growth rate (r)?

Accepted Answer

The percent change in a population over time

(10% growth rate -> the population increases exponentially by 10% each year)
