The diagram represents a pyramid of biomass in an aquatic environment. Which statement best explains why mass decreases from one level to the next in this pyramid?

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

Energy is lost to the environment at each level, so less mass can be supported at higher levels.

When organisms die at higher levels, their remains sink to the lower levels, increasing the mass at lower levels.

More organisms die at higher levels than that at lower levels, resulting in less mass at higher levels.
