The diagram shows a numbers pyramid for a forest community. Imagine that there is only one producer, a tree. This seems to contr
adict the concept of the typical food pyramid. All but one statement explains how this model is also correct. A) Chemical energy is transferred up from autotrophs to heterotrophs. B) The autotroph still has the greatest biomass and each level above is less. C) When producers are large, like forest trees, they can support numerous small primary consumers like insects and birds. D) The autotrophs would typically have the highest number of organisms with each level above it containing roughly 90% less.
