Understand how water cycles through the environment Know the four elements that cycle through ecosystems and why they are important. Understand the flow of each of the cycles discussed in 13.5. Which two biogeochemical cycles rely directly on photosynthesis? Which cycle do fossil fuels play a role in? Pyramid models (13.6) 1. Understand how energy pyramids show the distribution of energy among trophic levels. How many trophic levels are typically shown in energy pyramids? What do other pyramids show? 2. Why is energy lost at each level in the food chain? 3. Be able to recognize and label each type of pyramid discussed in 13.6.
