An energy pyramid is shown. Which sentence best describes how energy flows through this pyramid?

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

• No energy is lost as it is transferred to the next level.

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

• The organisms at the bottom level do not provide energy
