Final answer:
The complete food chain in order is: leaf, caterpillar, bird, snake, hawk
Step-by-step explanation:
The correct answer is: leaf, caterpillar, bird, snake, hawk. This is a complete food chain in order because it shows the transfer of energy from the sun (which the leaf uses for photosynthesis) to the caterpillar (which eats the leaf) to the bird (which eats the caterpillar) to the snake (which eats the bird) to the hawk (which eats the snake).
