What happens to the population of a species after it reaches its carrying capacity?

• Increases linearly (in a straight line) over time.

• Increases exponentially (line is curved) over time.

• Decreases to zero in a very short amount of time.

• Remains relatively the same.

Discuss the factors that contribute to population dynamics.

• Factors such as birth rates, death rates, immigration, and emigration contribute to population dynamics or size.

• Factors such as the number of trees and types of birds in the area

• Factors such as weather patterns and soil composition

• Factors such as the price of goods and availability of jobs
