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

emigration
immigration

What is carrying capacity in population ecology?
Maximum number of individuals a species can produce
Maximum number of individuals the environment can sustain
Average number of individuals in a population

List and explain the characteristics of a population.
Size, density, dispersion, age structure, and growth rate
Food availability, water source, shelter, predators, and competition
Climate, geography, economy, culture, and language
Color, weight, height, intelligence, and speed
Which of the following events would lead to an increase in the population of squirrels?
Birth rate > Death rate
Emmigration > Immigration
