Matter and Energy Flow Through the Biosphere

Matter and energy flow through the biosphere. The flow of matter, however, differs from the flow of energy. Which of the following statements accurately describes these differences?

A) Matter does not accompany energy as it enters the biosphere, but it does flow with energy from the biosphere.
B) Matter flows in cycles, whereas energy flows in one direction.
C) Energy flows as organic molecules are reduced to inorganic molecules, but matter does not.
D) Energy flows from chemotrophs to phototrophs, whereas matter flows from phototrophs to chemotrophs.
E) Matter and energy flow sometimes in cycles, sometimes unidirectionally.
