Potential essays:
1. Explain the differences between the Exponential and Logistic growth models. Include the equations
and diagram both curves.
2. Discuss the characteristics of r-selected and K-selected species. Draw the three survivorship curves.
3. List all of the different types of relationships organisms can have when they interact. Explain the
relationships giving examples of each. A chart may help you get started.
4. Explain primary and secondary succession and give an example of both.
5. Complete a water cycle by drawing all players in a cycle. Explain how water runs through its
complete cycle. What does the future hold for us if the water cycle is not modified?
2. 6. Explain conservation biology and the steps needed to make a change!
7. Explain the carbon cycle thoroughly a diagram will help identify the cycle then write the process.
8. Draw a food web and identify all of the players involved. Explain how much energy is lost as you go
up the food chain.
9. List and explain the different warning displays organisms can produce. Why are they important?
10. What type of diversity do oceans, freshwater and terrestrial physical habitats play a role in? Give
some examples of organisms that live in each area.
