Name the four factors that affect population growth. Then, explain how each factor contributes to population growth.
The four factors that affect population growth are birth rate, immigration, death rate, and emigration. Birth rate and immigration add individuals to the population, increasing its size. Death rate and emigration remove individuals from the population, decreasing its size. Population growth = (birth rate + immigration) − (death rate + emigration).
Which of the following did you include in your response? Check all that apply.
How are exponential and logistic growth models similar? How are they different?
Both models describe population growth and initially increase at a constant rate. Exponential growth continues when resources are unlimited, while logistic growth slows as resources become scarce and the population approaches carrying capacity.
