Question

Please help with my Biology study guide question!! I don't understand how to answer it on my sheet!

Describe how, and at what levels, decomposers operate within an ecosystem that has four trophic levels—producers, primary consumers, secondary consumers, and tertiary consumers. Provide examples of the role of decomposers on at least two of those levels.

Answer 2

I will give you a few hints for this, as it seems like a homework project.

Decomposers are the recyclers of the ecosystems. They breakdown nearby materials by excreting enzymes, and use the broken down materials as a food source. In other words, they eat the primary producers (being the plants that created the dead leaves).

Decomposers are very useful in taking dead matter and recycling it back into the food web. They do this, for example, by growing mushrooms, and then other animals eat the mushrooms.

Hope this helps you out on your homework.



Decomposers, as the name suggests, decompose dead plants or animals into simple compounds. They feed on dead producers from the first levels or consumers from other three levels. Breaking them down, decomposers release nutrients that producers can use.
In an ecosystem with four levels, the first level are producers, such as plants and algae. On the second trophic level, there are primary consumers, herbivores that eat plants, for example, a deer, a rabbit, a grasshopper. The next trophic level belongs to secondary consumers that eat herbivores, for example, a wolf, a fox. The highest level is tertiary consumers that eat carnivores, for example, a bear, an eagle.
