Essential Learning Outcomes & Ecosystem Connections
Essential Learning Outcome 1: Use models to describe that energy in animals' food was once energy from the sun.
Energy Transformation Process:
- Solar energy → Chemical energy (photosynthesis)
- Chemical energy transfer through food chains
- Energy loss at each trophic level (10% rule)
- Role of decomposers in energy cycling
Student Investigations:
- Track energy flow through local food chains
- Model photosynthesis using aquatic plants
- Investigate factors affecting plant growth
- Analyze energy pyramids and biomass
