Which of the following is at the second trophic level of a food chain?
Rats
In a food chain the producers (green plants such as grass) form the first trophic level and the primary consumers (herbivores) that eat them form the second trophic level.
Rats feed on plants and grains, so they are primary consumers at the second trophic level.
Snakes that eat rats are secondary consumers (third level) and eagles that eat snakes are tertiary consumers (fourth level), while grass is at the first level.
Hence, Rats.
