What are the two lower layers of the atmosphere? Cite at least two differences between them.
Explain why Earth’s temperature changes with latitude and with the seasons.
A geologist or physical geographer would describe the phosphorus cycle as a “sedimentary pathway.” Based on what you have learned about the phosphorus cycle in this chapter, what do you think that means?

Distinguish among energy, work, and heat.
What is the difference between a community and an ecosystem? Between an ecosystem and a landscape?
What is ecology?
Is it possible to have an inverted pyramid of energy? Why or why not?
Suggest a food chain with an inverted pyramid of numbers—that is, greater numbers of organisms at higher than at lower trophic levels.
Could you construct a balanced ecosystem that contained only producers and consumers? Only consumers and decomposers? Only producers and decomposers? Explain the reasons for your answers.
How are photosynthesis and cellular respiration related? Write the overall equation for both processes.
Give an example of a natural process in which order becomes increasingly disordered.
How is the first law of thermodynamics related to the movement of an automobile?
Is this an example of an open system or a closed system? Explain your answer. Energy input Energy output System Surrounding environment
