Question
how can a samll biomass of producers such as algae, support a larger biomass of consumers such as zooplankton?

Answer
Dear Rebecca,

If the producers (phytoplankton/algae) reproduce extremely rapidly--more rapidly than the zooplankton--then their biomass can actually be lower than that of the organisms that are eating them.  The zooplankton pretty much eat the algae as soon as it is produced in some ecosystems, giving us a surprise when it comes to analyzing the actual biomass that's supposed to be a pyramid--but turns out to be upside down!

:)

Hope that helps.

Experience

At the University of Miami, I teach Evolution and Biodiversity, Botany, Zoology, Genetics, Ecology, and a variety of seminars (e.g., the Biology and Evolution of Human Gender Roles).

Education/Credentials
I have a B.S. in Biology and an A.B. in English from the University of Southern California (1980). I earned my Ph.D. in Biology in the area of evolutionary biology/visual physiology from the University of Miami in 1989.
