As a general rule, total biomass _______, size of individuals _____, and number of individuals ______ as you move up a trophic pyramid or through a food web.
The answer is decreasing….increases….decreases.
The reason behind this is that the higher you go up the food web the lower the energy
is transferred up the chain. Only 10% of energy
is passed from one trophic level to another (in biomass) as you go up the food web. The other 90% is lost through
entropy. This is why the energy pyramid
takes the shape of a pyramid.
