Detailed explanation-1: -Primary consumers are herbivores, feeding on plants. Caterpillars, insects, grasshoppers, termites and hummingbirds are all examples of primary consumers because they only eat autotrophs (plants). There are certain primary consumers that are called specialists because they only eat one type of producers.

Detailed explanation-2: -Both primary (herbivores) and secondary (carnivores and omnivores) consumers are heterotrophs, while primary producers are autotrophs.

Detailed explanation-3: -Examples of large herbivores include cows, elk, and buffalo. These animals eat grass, tree bark, aquatic vegetation, and shrubby growth. Herbivores can also be medium-sized animals such as sheep and goats, which eat shrubby vegetation and grasses. Small herbivores include rabbits, chipmunks, squirrels, and mice.

Detailed explanation-4: -An herbivore is an organism that feeds mostly on plants. Herbivores range in size from tiny insects such as aphids to large, lumbering elephants.

Detailed explanation-5: -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.
