Objectives
• To state that members of an ecosystems require a continuous supply of energy to fuel life processes and to replace energy lost as heat
• To explain the relationship between experimental results and larger biological concepts, processes, or theories
• To describe the strategies organisms utilize to acquire and use energy
• To explain how the activities of autotrophs and heterotrophs enable the flow of energy within an ecosystem
• To design and carry out an investigation to answer a question regarding the capture of energy from sunlight, the energy dynamics, and the allocation of energy between the organisms of an ecosystem
• To examine, calculate, and comment on the energy flow in an ecosystem by preparing a model using one animal and one plant
