Option 2 : Detritivores

The correct answer is Detritivores.

  • Detritivorous animals include millipedes, springtails, woodlice, dung flies, slugs, many terrestrial worms, sea stars, sea cucumbers, and fiddler crabs.
  • Decomposers (detritivores) break down dead plant and animal material and wastes and release them again as energy and nutrients into the ecosystem for recycling.
  • Decomposers, such as bacteria and fungi (mushrooms), feed on waste and dead matter, converting it into inorganic chemicals that can be recycled as mineral nutrients for plants to use again.

  • Trophic levels can be represented by numbers, starting at level 1 with plants.
  • Further trophic levels are numbered subsequently according to how far the organism is along the food chain.
    • Level 1: Plants and algae make their own food and are called producers.
    • Level 2: Herbivores eat plants and are called primary consumers.
    • Level 3: Carnivores that eat herbivores are called secondary consumers.
    • Level 4: Carnivores that eat other carnivores are called tertiary consumers.
    • Level 6: Decomposers.
