Detailed explanation-1: -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-2: -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-3: -The primary consumers are herbivores (vegetarians). The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers.

Detailed explanation-4: -Primary consumers can be herbivores and eat only plants, or they can be omnivores and eat plants and animals. Primary consumers are first-level consumers and are on the trophic level number two above plants.

Detailed explanation-5: -Secondary consumers are organisms that eat primary consumers for energy. Primary consumers are always herbivores, or organisms that only eat autotrophic plants. However, secondary consumers can either be carnivores or omnivores.
