Final answer:
The organism at the third trophic level is the snakes.
Step-by-step explanation:
In this food chain, the organism at the third trophic level is the snakes. Trophic levels represent the positions that organisms occupy in a food chain, and they indicate the flow of energy through the ecosystem. In this case, the grass is at the first trophic level as it is the primary producer. The rabbits are at the second trophic level as they consume the grass. The snakes, as tertiary consumers, occupy the third trophic level as they consume the rabbits. The hawks and foxes would be at higher trophic levels as they consume animals from lower trophic levels.
