Every time you move up a stage (trophic level) in a food chain there is...
A. 
More energy
B. 
Less energy
C. 
More biomass
D.

2.
There is usually a fewer _________ of organisms as you move up a trophic level as well

Each bar on a pyramid of biomass = how much each level would 'weigh' if you put all the animals together.
So the fox would have a much ______ biomass than the fleas
