      All living things in the forest rely on each
      other for food. These links can be shown
      in a food chain. All food chains need

      a producer, a consumer, and a decomposer
      to work well. If just one part of the food                      Producer

      chain disappears, then it may cause many                        Food chains start with a

                                                                      plant. Plants are producers
                                                                      because they make their own

                            chirping primary consumers in
                            forests. They like to eat plants.

                            growing, but are worn down by
                            all the grass they eat.                                                                    Deer

                            small worms. They eat dead flesh,
                            helping to recycle animal bodies.                Food chains usually
                                                                             start with a plant.
