The Role of Decomposers in the Ecosystem Science 8 9/ 17 /07

What are Decomposers? Decomposers: (defined) Organisms that use dead plant and material as food.

Niche Decomposers break down material, getting the energy they need to live and releasing elements back into the environment to be reused by other organisms.

Decomposers at Work

Decomposers are…. Simple plants such as bacteria and fungi. Most are microscopic organisms

Decomposers in the Pond Ecosystem Located everywhere but more abundant at the bottom. Dead plants and animals settle. That is why the pond muck smelled bad

Decomposers in the Forest In the forest abundant in the top layers of the soil

Niche 2 Decomposer are the janitors of nature. Composting
