• Decreases
• Stays the same
• Changes up and down

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