Energy Flow in Ecosystems
Bozeman Science
Guided Notes
Key concepts students will learn:
- •
The major source of energy on our planet is the sun, which plants convert into usable energy through photosynthesis.
- •
Gross primary productivity is the overall amount of energy converted by producers, while net primary productivity is the energy remaining after the producers' respiration.
- •
In an ecological pyramid, only about 10% of the energy from one trophic level is transferred to the next level, with the rest being lost as heat.
Practice
12 questions • Multiple choice & Short answer
Exit Ticket
“Draw an ecological pyramid representing energy flow in a forest ecosystem. Label each trophic level (producers, primary consumers, secondary consumers, tertiary consumers) and indicate the relative amount of energy available at each level, assuming a 10% transfer efficiency between levels.”
