Insects as Decomposers — page 3 — Many decomposers are not visible Broadly they are fungi bacteria and invertebrates They are living things that get their energy from eating dead animals and plants and breaking down wastes of other animals When a plant or animal dies nutrients would remain in the dead tissues if it weren’t for decomposers They complete the life cycle by returning important molecules to plants They release nutrients creating fertile soil 6

Insects as Decomposers — page 4 — Invertebrates are animals without a backbone They skitter slide and wiggle their way through soil Each invertebrate has a job Sow bugs eat decaying leaves and carry bacteria and fungi on their backs Snails and slugs chew rotting material into small pieces for millipedes and beetles to eat Poop Scoop Termites are decomposers that aren’t born with bacteria in their digestive tracts To correct this they practice trophallaxis They eat each other’s poop 7
