Detailed explanation-1: -A) Trophic level: corn-level 1; mouse-level 2; corn snake-level 3; hawk-level 4 trophic status: corn-producers; mouse-primary consumers; corn snake-secondary consumers; hawk-tertiary consumers.

Detailed explanation-2: -Level 2: primary consumers The next trophic level in a food chain or an ecological pyramid is trophic level 2. In this level, the organisms occupying this level feed on the primary producers and are called primary consumers. Animals that feed on plant materials are called herbivores.

Detailed explanation-3: -Second Trophic Level: Primary Consumers Herbivores are placed in this trophic level of the food chain. They depend upon the autotrophs to meet their food requirements and include organisms like insects, cows, and pigs.

Detailed explanation-4: -The first and lowest level contains the producers, green plants. The plants or their products are consumed by the second-level organisms-the herbivores, or plant eaters. At the third level, primary carnivores, or meat eaters, eat the herbivores; and at the fourth level, secondary carnivores eat the primary carnivores.
