The diagram represents a model of a food pyramid. Which statement best describes what happens in this food pyramid?

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

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

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

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