Level Check #2 - Carrying Capacity & Population Dynamics

What is the carrying capacity of an environment?

• The minimum population an environment can support
• The maximum population an environment can support long-term
• The average number of species in an ecosystem
• The total number of resources available

What is population density?

• a measurement of how smart a population is in a given area
• a measurement of how many organisms live in a given area
• a calculation of the average number of individuals in an ecosystem
• the birth rate and death rate averaged together for humans in various areas

Which of the following is a biotic factor?

• Food
• Water
• Shelter
• Oxygen

Does the number of organisms in an area affect the predator prey relationship causing it to be a limiting factor?

• Yes
• No
• They are not connected (density-independent).
• It depends on the environment or abiotic factors.

Are natural disasters, like wildfires, a limiting factor that depends on how many organisms are in a given area?

• Yes
• No
• They depend on the number of individuals.
• It depends on the history of the given area.

What is population density?

• The total number of individuals in a population
• The number of individuals divided by the size of the area
• The carrying capacity of an environment
• The growth rate of a population

What happens to the population when it exceeds the carrying capacity?

• It continues to grow exponentially
• It stabilizes at the new level
• It declines due to lack of resources
• The environment expands to accommodate it
