Part Two: What Limits The Size Of Populations? Read Page 73 1. What is a limiting factor?

2. Provide some examples of limiting factors.

3. What are two ways climate or weather can be limiting factors? 1. 2.

Read Pages 74 and 75 4. What are examples for how space is a limiting factor for the following organisms? Animals - Plants -

5. What is one example of how food and water can limit the size of a population? Food - Water -

6. What is carrying capacity?

7. After reading the apply it section, what are some limiting factor for pandas? Why?

8. Is the carrying capacity for Pandas high or low? Why?

9. What can be done to increase the carrying capacity of pandas in the wild?

Watch, “Carrying Capacity” Why would a species being over carrying capacity negatively impact an ecosystem?

Why is the sturgeon’s carrying capacity high in Lake Winnebago?

What do scientists do to ensure an optimal carrying capacity?

Watch, “Why Is This Island Chock Full Of Rabbits” In terms of population ecology, how could you explain the phenomenon of Rabbit Island?

Watch, “How Wolves Change Rivers” Why are limiting factors and carrying capacity important for an ecosystem?

Watch, “Why Do Animals Go Extinct” Ecology Unit Lesson Two Assessment: Endangered Species Poster
