Final answer:
Organisms in a food web can be categorized by the number of 'trophic levels' they are away from a producer, which represents their position in the flow of energy within an ecosystem.
Step-by-step explanation:
Even though a food web doesn’t look like a pyramid, organisms can be categorized by counting how many “trophic levels” away from a producer they are. A grazing food web, which typically has plants or photosynthetic organisms at its base, is followed by herbivores and various carnivores in subsequent trophic levels. In contrast, a detrital food web is based on organisms that feed on decaying organic matter and includes decomposers and detritivores like bacteria and fungi. These decomposers play a crucial role in recycling organic materials back into the ecosystem. Organisms in higher trophic levels, such as carnivores, will be further “steps” away from the producers than herbivores, which are typically one “step” away as they consume the producers directly.
