Learning goals
- Differentiate producers (plants), primary consumers (herbivores), secondary consumers (carnivores), and decomposers
- Trace energy arrows showing flow from organism consumed to consumer
- Explain the role of the Sun as the primary energy source in nearly all ecosystems
Before you begin
Recognize that living things obtain energy in different ways.

Teaching and response guide
- Model the target skill: differentiate producers (plants), primary consumers (herbivores), secondary consumers (carnivores), and decomposers. Use the first task as a guided example before asking for an independent response.
- Check readiness first: Recognize that living things obtain energy in different ways.
- Discuss an incorrect response using this distinction: Food-chain arrows show the direction of energy transfer, from the eaten organism toward the consumer.
Watch for: Food-chain arrows show the direction of energy transfer, from the eaten organism toward the consumer.
Check the answer criteria for each task. A supported explanation may have more than one acceptable response. These activities offer evidence to discuss; completing a sheet alone does not establish mastery.
