Which sentence best describes how energy flows through this pyramid?

• The organisms at the bottom level provide energy directly to organisms in all the other levels.

• Energy is transferred from organisms in one level to those in the level above.

• The energy lost at each level is consumed by organisms in the top level

• Energy is transferred down each level of the energy pyramid.
