Question

based on the food web, which of these organisms receives its energy directly from a primary consumer?
a. caterpillar
b. dandelion
c. frog
d. grasshopper

Explanation:

Primary consumers are organisms that eat producers (plants). In the food web, caterpillar (A) eats dandelion (a producer). Dandelion (B) is a producer. Frog (C) and grasshopper (D) are not directly getting energy from a primary source (producer) as per the question's context (the arrow direction in food - web implies who is eaten by whom. If the question was about which is a primary consumer in general, grasshopper is also a primary consumer, but based on the 'from a primary source' (assuming producer as primary source here) and the options, caterpillar eats dandelion (producer) directly.

Answer:

A. caterpillar
