Grades 9-12. Students examine microorganisms and create a food chain based on observed feeding patterns. Students explore energy transfer through different trophic levels of a food chain using a simulation activity. Using their finding that all energy is not transferred, students calculate the energy flow through the food chain they created. Kit accommodates 30 students working in pairs.
Construct a model food chain for a system of microorganisms and develop a mathematical model for energy transfer between trophic levels.
