    • Producer
    • Decomposer

  3. Decomposers such as fungi and bacteria break down dead material.

    Circle one:   True   False

  4. A grasshopper eats a plant's leaves. A bird eats the grasshopper. What makes the grasshopper a primary consumer in this chain?

    • It makes its food from sunlight
    • It eats food directly from a plant
    • It eats an animal that eats plants

  5. An insect eats leaves from a rainforest plant. A small frog eats the insect. Which food-to-eater order builds this chain?

    • Plant, insect, frog
    • Frog, insect, plant
    • Plant, frog, insect

  6. A monkey eats figs, a toucan eats figs, and a jaguar hunts monkeys. How many consumers are described?

    Answer: ______________

  7. Decomposers break down a dead jaguar. Which statement correctly describes nutrients and energy?

    • Nutrients turn into sunlight, while energy stays in soil for plants
    • Nutrients leave forever as heat, while energy cycles through plants
    • Nutrients can be reused by plants, while energy eventually leaves as heat

  8. A caterpillar eats tree leaves, and a bird eats the caterpillar. A beetle eats shrub leaves, and the same kind of bird eats the beetle. What connects these food chains?

    • Both chains happen in one forest, even without any shared eater
    • The same kind of bird is an eater in both feeding paths

  1. Consumer · The monkey obtains food from a plant, so it is a consumer.
  2. Producer · A plant making its own food is a producer.
  3. True · Fungi and bacteria obtain food by breaking down dead material and wastes.
  4. It eats food directly from a plant · The grasshopper eats leaves directly from the plant, so it is the primary consumer. The bird has a different feeding level in this chain because it eats the primary consumer.
  5. Plant, insect, frog · The plant supplies food to the insect, and the insect supplies food to the frog. The order is plant, insect, frog.
  6. 3 · The monkey, toucan and jaguar each obtain food by eating. All three are consumers.
  7. Nutrients can be reused by plants, while energy eventually leaves as heat · Roots can take up released nutrients. Energy eventually leaves as heat rather than cycling like nutrients.
  8. The same kind of bird is an eater in both feeding paths · The bird appears in both paths. Keeping its feeding links to the caterpillar and beetle joins the chains into part of a food web.
