Why does the distribution of benthic biomass mimic the distribution of surface water biomass?
a) these are areas of downwelling, where surface waters sink, providing nutrients for benthic organisms
b) these areas of high productivity occur in the same location because these locations have the best environment
c) food for most benthic organisms sinks to the seafloor from overlying surface water
d) most of these places are shallow where sunlight penetrates to the seafloor, so photosynthesis can occur both in the water column and on the seafloor
e) these areas have higher temperatures that are conducive to high productivity, whether it is benthic or pelagic
