Question

question 4
what happens to the matter from producers that consumers eat?
a. the producers matter begins to fall apart and lose its energy.
b. the producers matter becomes part of the predator’s matter.
c. the producers matter disappears entirely because the prey dies.
d. the producers matter is discarded by the predator because it is not useful.

Explanation:

To solve this, we analyze each option:

• Option A: Matter doesn't "fall apart" and lose energy in this context; energy changes form, but matter is conserved. Eliminate A.
• Option B: When consumers (predators) eat producers (or prey), the matter from the producers is digested and assimilated, becoming part of the predator's body (matter is conserved in ecosystems, moving through trophic levels). This matches ecological principles.
• Option C: Matter doesn't disappear entirely; it's transformed or transferred. Eliminate C.
• Option D: Producers' matter (like plants) is useful as food, providing nutrients/energy. Predators don't discard it as useless. Eliminate D.

Answer:

B. The producers' matter becomes part of the predator’s matter.
