Question

what statement holds true for the amount of matter in a successful food web?
a amount of matter contained in the producers and consumers should be equal.
b amount of matter produced by the producers should be more than that of the consumers.
c amount of matter contained in the consumers should be more than that of the producers.
d amount of matter produced by the producers should be negligible when compared to the consumers.

Explanation:

In a food web, producers (autotrophs) create organic matter via photosynthesis/chemosynthesis. Consumers (heterotrophs) rely on producers for matter. A successful food web requires producers to generate enough matter to support all consumer levels, so producer-produced matter must exceed consumer matter.

Answer:

B. Amount of matter produced by the producers should be more than that of the consumers.
