5�2 Limits to Growth
 
1.  Key Concept List three density-dependent factors and three density-independent factors that can limit the growth of a population.
2. What is the relationship between competition and population size?
3. If an entire lynx population disappears, what is likely to happen to the hare population on which it preys?
4. Identify how a limited resource can affect the size of a population. Give an example that illustrates this situation.
5. Critical Thinking Applying Concepts Give an example of a density-independent limiting factor that has affected a human population. Describe how this factor changed the human population.


Biotic and Abiotic Factors

Study the factors that limit population growth as shown in the figure Limiting Factors. Classify each factor as either biotic or abiotic. Refer to the information on biotic and abiotic factors in Section 4-2.
