Acacia trees
Impala
Vulture
The diagram represents a model of a biomass pyramid. Which statement best describes what happens in this biomass pyramid?
Organisms decay at each level, and thus less biomass can be supported at higher levels
Energy is lost to the environment at each level, so less biomass can be supported at each higher level.
When organisms die at higher levels, their remains sink to lower levels, increasing the biomass of lower levels.
More organisms die at higher levels than at lower levels, resulting in less biomass at higher levels.
