Question

Using the food web, describe two complete food chains that include a producer, consumer, and decomposer.
A food web showing many food chains. Producers are tree and grass. Primary consumers are caterpillar, deer, bird, chipmunk, rabbit, grasshopper, spider. Secondary consumers are bird, spider, owl, mouse, fox, hawk. Decomposer is mushroom.

Answer 1

Here are two complete food chains using organisms from the web. Each shows a producer, consumers, and the decomposer that recycles nutrients.

1) Tree (producer) → Caterpillar (primary consumer) → Bird (secondary consumer) → Mushroom (decomposer)
- The tree makes energy by photosynthesis. The caterpillar eats the tree leaves. A bird eats the caterpillar. When the bird (or any organism in the chain) dies, the mushroom breaks down the body and returns nutrients to the soil.

2) Grass (producer) → Rabbit (primary consumer) → Fox (secondary consumer) → Mushroom (decomposer)
- Grass produces energy from sunlight. The rabbit eats the grass. The fox preys on the rabbit. The mushroom decomposes remains and returns nutrients to support the producers.
