Population Ecology

What is the carrying capacity of the graph?

• around 500
• more than 500
• less than 500
• around 600

What is the carrying capacity of the following graph?

• 1000
• 8000
• 800
• 600

The total number of individuals a habitat can survive with the resources it has available.

• Carrying capacity
• Limiting factors
• Resources
• Population

If the amount of food or resources available increases, the carrying capacity for an animal:

• Stays the same
• Increases
• Decreases
• Fluctuates

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

Check all of the boxes that are examples of abiotic factors.

• Prey

• Rainfall

• A pack of wolves

• A tornado

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
