Unit 6 Flow of Energy

What sentence best describes how energy flows through this pyramid?

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

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

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

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