Key Concepts

  • Producers (plants)
  • Consumers (animals)
  • Decomposers (bacteria/fungi)
  • Flow of energy in an ecosystem

Learning Objectives

  • Identify and define producers, consumers, and decomposers.
  • Explain how energy flows through a food chain.
  • Give examples of different organisms at each level of the food chain.

Educator Instructions

  • Introduction (5 mins)
    Begin by asking students what they ate for breakfast, lunch, or dinner. Lead a brief discussion about where that food comes from. Introduce the idea that all living things are connected through what they eat.
  • Video Viewing (10 mins)
    Watch the "The Food Chain for Kids" video by Homeschool Pop. Encourage students to pay attention to the definitions and examples of producers, consumers, and decomposers.
  • Producers Discussion (10 mins)
    Discuss producers, emphasizing that plants make their own food using sunlight, water, and air. Ask students to name different types of plants that are producers (trees, grass, flowers, etc.). Relate this to standard 2.LS2.1 by mentioning that plants need sunlight and water to grow.
  • Consumers Discussion (10 mins)
    Explain that consumers are animals that eat other plants and animals. Discuss different types of consumers: herbivores (eat plants), carnivores (eat animals), and omnivores (eat both). Ask students to give examples of each type of consumer. You can explain that an animal that eats other animals in an ecosystem are often referred to as predators. The prey are the animals that the predators eat.
  • Decomposers Discussion (5 mins)
    Explain that decomposers break down dead plants and animals, returning nutrients to the soil. Discuss examples of decomposers like worms, bacteria, and fungi. Talk about how this helps plants grow.
  • Review (5 mins)
    Briefly review the roles of producers, consumers, and decomposers in the food chain. Emphasize how energy flows from the sun to plants to animals.
  • Assessment (10 mins)
    Have the students complete the fill in the blank and multiple choice quizzes. Use the results from the quizzes as a formative assessment tool. Review student performance and clarify any misunderstood concepts.

Interactive Exercises

  • Food Chain Creation
    Provide students with pictures of different plants and animals. Have them create their own food chains by arranging the pictures in the correct order, showing the flow of energy. This could be done individually or in small groups. Have the students explain why their food chain is in that order.

Discussion Questions

  • What would happen if there were no plants?
  • Why are decomposers important?

Skills Developed

  • Observation
  • Classification
  • Critical Thinking
