Question

which trait of a marine animal is most closely linked to the depth of its habitat, such that it can reliably be used to infer which zone the animal lives in? a. its food source b. its coloring c. its shape d. its size

Explanation:

Marine animals' coloring relates to depth - e.g., counter - shading in mid - water (darker on top, lighter below) for camouflage. Food source, shape, and size are less directly tied to depth zones for reliable inference.

B. its coloring
