What organism absent in the web would be MOST responsible for recycling organic matter back through food web?

The organism that is absent in the food web and would be most responsible for recycling organic matter back through the food web is a decomposer. Decomposers are organisms that break down dead plant and animal matter, releasing nutrients back into the soil or water. This process is essential for recycling organic matter and keeping the ecosystem healthy. Some examples of decomposers include bacteria, fungi, and earthworms.

In the provided food web, there are no decomposers present. This means that the dead plant and animal matter that accumulates in the ecosystem will not be broken down and recycled, which will eventually lead to a decline in the health of the ecosystem.
