Question

which organism is at the top of the food chain pictured?
grass
the sun
fox

Explanation:

In a food chain, producers (like grass) are at the bottom, the sun is a non - living energy source, and top predators (like fox) are at the top as they have few or no natural predators and consume other organisms. Grass is a producer, the sun is not an organism, so the fox is at the top of the food chain.

Answer:

C. fox (assuming the options are labeled as A. grass, B. the sun, C. fox)
