What are decomposers and give 2 examples
Decomposers are organisms that feed on dead animals and plants. Examples of this would be bacteria and fungi.
Why are decomposers important?
They release the minerals locked up in dead animal and plant material and return them to the soil.
What is the feeding level and what level does a green plant occupy ?
The feeding level is the position an organism has in the food chain. The first feeding level is always occupied by a green plant.
