Practical Applications

Building a Simple Food Web

Make a Food Web Poster

Gather pictures or draw animals and plants you know. Arrange them on a poster and use arrows to show who eats whom.

Steps

  1. Draw or cut out pictures of plants and animals.
  2. Arrange them into groups (plants, herbivores, carnivores).
  3. Use arrows to connect what eats what.
  4. Share your food web with friends or family!

This helps you see how energy moves through an ecosystem.

Examples

  • Link grass to a grasshopper, grasshopper to a frog, frog to a snake.

  • Show how a bird can eat both seeds and insects, connecting different chains.
