Biomass of heterotrophs may be greater than the biomass of autotrophs but
energy produced by autotrophs is still greater
Inverted biomass pyramids is greatest where productivity is lowest (ex:
nutrient poor regions of the open ocean)
Reason you can support large animals with little biomass –phytoplankton turn
over really quickly (get consumed but are replaced quickly; high supply)
is and be able to explain where energy in food goes.
should also know rough estimates of production efficiency and be able to calculate it.
more or less efficient?
Know estimated values of ecological efficiency and be able to
Explain the junk food hypothesis with regard to
Stellar sea lions
Be familiar with top-down, bottom-up control and trophic cascades.
