Skills
- diagram (the flow of energy within trophic levels) #dok2
- describe (how available energy decreases in successive trophic levels in energy pyramids) #dok2
Learning Targets
- I can identify the flow of energy through different trophic levels in an ecosystem. #dok1
- I can define trophic levels and energy pyramids. #dok1
- I can diagram the flow of energy within trophic levels using an energy pyramid. #dok2
- I can describe how available energy decreases at each successive trophic level in an energy pyramid. #dok2
- I can explain why energy decreases in higher trophic levels using examples from real ecosystems. #dok3
Big Ideas
- Energy flows in one direction through ecosystems and decreases at each trophic level.
- Energy pyramids illustrate the reduction of available energy at higher trophic levels.
Essential Questions
- What is a trophic level, and how does it relate to the flow of energy in an ecosystem?
- How does energy move through the different levels of an energy pyramid?
- Why does the amount of available energy decrease at each step up the energy pyramid?
- What happens to the energy that is not transferred to the next trophic level?
- How do energy pyramids help us understand the structure of ecosystems?
