Food webs are evidence that
A.

B.
living systems follow the laws of conservation of mass and energy.
C.
more matter must be created because mass is used up once it is transferred to decomposers.
D.
consumers require more energy than producers and decomposers.

B. Food webs show that matter and energy are transferred and recycled among producers, consumers, and decomposers, consistent with the conservation of mass and energy (no new mass is created or destroyed, it is just transformed and moved).
