Detailed explanation-1: -The second trophic level consists of herbivores, these organisms gain energy by eating primary producers and are called primary consumers. Trophic levels three, four and five consist of carnivores and omnivores.

Detailed explanation-2: -Primary consumers, which form the pyramid’s second level, are herbivores (such as leaf-eating insects) that dine on producers; however, omnivores (animals that can eat both plants and other animals), such as opossums or raccoons, might also qualify as primary consumers if they feed exclusively on plant material.

Detailed explanation-3: -Primary consumers are herbivores. Herbivores eat plants, algae, and other producers. They are at the second trophic level. In a grassland ecosystem, deer, mice, and even elephants are herbivores.

Detailed explanation-4: -Primary consumers make up the second trophic level. They are also called herbivores. They eat primary producers-plants or algae-and nothing else. For example, a grasshopper living in the Everglades is a primary consumer.

Detailed explanation-5: -The second trophic level consists of organisms that eat the producers. These are called primary consumers, or herbivores. Deer, turtles, and many types of birds are herbivores. Secondary consumers eat the herbivores.
