19.
The diagram represents a model of a food pyramid. Which statement best describes what happens in this food pyramid?
a)
More organisms die at higher levels than at lower levels, resulting in less mass at higher levels.
b)
Energy is lost to the environment at each level, so less mass can be supported at each higher level.
c)
When organisms die at higher levels, their remains sink to lower levels, increasing the mass of lower levels.

Organisms decay at each level, and thus less mass can be supported at higher levels
