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
