Food webs are evidence that
A.
living systems follow the laws of conservation of mass and energy.
B.
consumers require more energy than producers and decomposers.
C.
there are more producers than consumers or decomposers in living systems.
D.
more matter must be created because mass is used up once it is transferred to decomposers.

Answer 1

A.

Food webs show the transfer and recycling of energy and matter between producers, consumers, and decomposers, which is consistent with the conservation of mass and energy. The other options are incorrect: B is not generally implied by a food web, C is not necessarily true, and D contradicts the conservation principle.
