Which trophic levels would be impacted by lower yields of fungi (mushrooms) due to, for example, acid rain?
tia_tia [17]

Fungi belong to the decomposer topic level because they decompose organic matter and return the elements to the producer for reuse. Therefore, if mushrooms have low yields, less material to break down, and fewer minerals are available to them, they will be directly affected.

It also indirectly affects everything above the nutritional stage, which depends on the producer.

Another nutritional stage, the decomposer or transformer, is composed of organisms such as bacteria and fungi that break down dead organisms and waste into nutrients that the producer can use.

The decomposer forms the final trophy level. When living things produce waste or die, inanimate objects remain. Nutrients and organic matter are trapped in this substance. Decomposers like fungi break down waste and return it to raw nutrients.

In a system of five trophic levels, organisms are classified according to their lifestyle. The five levels include primary producers (plants), primary consumers (herbivores), secondary consumers, tertiary consumers, and detritivores (decomposers).
