Critical Thinking: ​Answer the following question with a claim, evidence, and explanation.
Chapter 1:
1. What is the role of energy in living organisms?
2. Compare and contrast a response and an adaptation.
3. Evaluate the statement, “Scientists just perform experiments to prove what they already
believe.”
Chapter 2:
1. Explain why it is advantageous for organisms such as fungi and algae to form mutualistic
relationships.
2. Explain the difference between a habitat and a niche.
3. Describe why food webs are generally better models for explaining energy flow than food
chains.
4. Clarify what is meant by the following statement: Grass is just as important as mice in
the diet of a carnivore such as a fox.
5. The law of conservation of matter states that matter cannot be created or destroyed.
How does this law relate to the cycling of carbon in an ecosystem?
Chapter 3:
1. Generalize the difference between a successional stage and a climax community.
2. Infer whether species diversity increases or decreases after a fire on a grassland.
Explain your response.
3. Explain why the concepts of limiting factors and tolerance are important in ecology.
4. Describe how successsional stages would differ from primary succesion.
5. In December 2004, a huge iceberg caused a large number of penguin chicks to die of
starvation. Ice shelves broke apart in areas where the air temperature increased. The
parents of the penguins were cut off from their food source. How is this an example of
temperature as a limiting factor?
6. Suggest why biomes are classified according to their plant characteristics rather than
according to the animals that inhabit them.
7. Classify a biome that is warm to hot in the summer and cool or cold in the winter and that
receives approximately 50-89 centimeters of precipitation annually.
Chapter 4:
1. How does the carrying capacity affect k-strategists?
2. Give two examples of how two different density-independent factors can limit a specific
population.
3. Explain how competition limits a population’s growth.
4. Predict the shape of a population growth curve for a game park in which a male and
female rhinoceros are released.
5. Opossums are solitary animals that usually meet in nature only to mate. What is their
probable dispersion pattern?
6. Why might a population continue to grow when the number of births equals deaths?
7. Hypothesize the shape of the age diagram for Switzerland, a developed country in
Europe.
Chapter 5:
1. Infer why there is more species diversity in southern Florida than there is in northern
Alaska.
2. Explain why increased ecosystem diversity contributes to increased biodiversity in the
biosphere.
3. Describe three values that the biosphere provides.
4. Describe a service that an ecosystem provides in your community that should be
protected to ensure that the quality of the service continues.

2. What are the two most fragile biomes? What are the greatest threats to their continuity?
3. Which biome was more prevalent when fossil fuels formed? How did they form fossil
fuels?
4. Which biome is characterized by lack of water? Give three examples of organisms that
live there that have adapted to water scarcity and explain what their adaptation is.
