Enrichment - Environmental change & Carrying Capacity

What is an Abiotic Factor?

• A NON-living factor that can affect an ecosystem

• A living factor that can affect an ecosystem

• The carrying capacity of an ecosystem

What is a Biotic Factor?

• The carrying capacity of an ecosystem

• A NON-living factor that can affect an ecosystem

• A living factor that can affect an ecosystem

Check all of the boxes that show examples of biotic factors.

• Rain

• Humans hunting

• Predators

• Wildfire

What is a limiting factor?

• Factors that always increase a population

• Factors that always decrease a population

• Resources that are unlimited

• Factors/resources that limit how many organisms can live in an area at the same time

If there was a wildfire in the forest that destroyed the plant life, what would happen to the herbivore population?

• Herbivores would decrease due to a lack of food

• Herbivores would increase due to an increase of food

• Herbivores would not be affected

• Herbivores would decrease due to an increase in predators

What is a population?

• All the organisms living in an area

• The living and non-living organisms in an area

• A group of the same species living in an area

Can a population go over its carrying capacity?

• Yes

• No

• Maybe

What happens if a population goes over its carrying capacity?

• It will continue to grow

• It will eventually decrease due to a lack of resources

• It will die immediately

• It will get unlimited resources

Which of the following would cause an increase in the omnivore population?

• Increase in carnivores

• Humans hunting

• Increase in competition

What is the overall trend of this population graph?

• Increasing
