Determine the concept of numeric pyramid, Biology

Assignment Help:

In a numeric pyramid to which trophic level does the base always refer? What about the top level?

In a numeric pyramid the base corresponds to the first trophic level, i.e., to the producers. The top level of the pyramid corresponds normally to the last consumer order of the food chain (as the number of individual decomposers, most of them microorganisms, is too large to be shown).
