2B) Pyramidal Analysis of Biotic Relationships
Explanation to follow below
In our trophic pyramid, you will notice that two species, the earthworm (Lumbricus Terrestris) and the artist's fungus (Ganoderma applanatum), are placed outside in a separate region. The reason for this is that they are decomposers. They would be placed in the herbivores section, however the decomposer takes precedence.
The rest of the organisms are placed in their respective levels of the trophic pyramid, autrophs, herbivores, carnivores, or omnivores.
