Why does an ecosystem need decomposers

Decomposition: The action or process of breaking down; the rotting or decaying of plant or animal matter. Or: food. Organic waste: Waste created by or from a once-living organism.

It is capable of decay and is composed of carbon compounds. Science World Decomposer Photo Cards. Metro Vancouver Worm Composting Brochure. Objectives List and identify examples of decomposers and describe their role within a simple food web. Differentiate between compostable waste and non-biodegradable waste. Explore the active process of decomposition. Create a worm compost farm.

Materials See activities for materials. Background Energy enters the food chain from the sun. Vocabulary Biodegradability: Biological and biochemical breakdown of organic materials by the environment.

Invertebrate: An animal that lacks a backbone or spinal column. Not only are they a healthy part of our meals, providing nutrients,…. Backyard Biodiversity Who do we share our homes with? What is a producers role in a ecosystem? What is an example of a producer? Is a frog a producer or a consumer? Which is more important: producers or decomposers?

What is an example of a decomposer? What would happen if decomposers were absent from a forest ecosystem? What does the term 'thermal decomposition' mean? See all questions in The Role of Decomposers. Impact of this question views around the world. Other decomposers are big enough to see without a microscope. They include fungi along with invertebrate organisms sometimes called detritivores, which include earthworms, termites, and millipedes.

Fungi are important decomposers, especially in forests. Some kinds of fungi, such as mushrooms, look like plants. But fungi do not contain chlorophyll , the pigment that green plants use to make their own food with the energy of sunlight. Instead, fungi get all their nutrients from dead materials that they break down with special enzymes. The next time you see a forest floor carpeted with dead leaves or a dead bird lying under a bush, take a moment to appreciate decomposers for the way they keep nutrients flowing through an ecosystem.
