Based on the graph, what happens to a population as it reaches the carrying capacity of an ecosystem.

• Population continues to increase.
• Population will decrease.
• Population remains constant.

The largest number of organisms from a particular species that can live in an ecosystem at one time is the __________ for that species in that ecosystem

• symbiosis
• carrying capacity
• sample count

What does a population undergo when it has no limiting factors?

• extinction
• migration
• exponential growth

Why is it impossible for any species to reach their biotic potential?

• Reaching biotic potential would require the extinction of all other species.
• No ecosystem possesses unlimited resources and no limiting factors, which would be required for a species to reach the biotic potential.
• As long as there are too many producers the biotic potential cannot be reached.

What is required for a species to experience exponential growth?

• hostile conditions, unlimited resources
• limited resources, ideal conditions
• ideal conditions, unlimited resources

• carnivore.
