Metabolism: all chemical reactions within a cell
Energy is lost as you go up the trophic levels. Therefore the trophic level with the least amount of energy is the secondary consumers.

Answer:
Affected animals given a galactokinase inhibitor do not experience toxicity.
Explanation:
Galactokinase: Catalyzes is the first and committed step of the Leloir pathway involving the conversion of galactose to glucose. It causes phosphorylation of α-D-galactose to galactose 1‑phosphate. Thus, inhibiting galactokinase wil greatly decrease the levels of galactose 1‑phosphate.
