Detailed explanation-1: -The organisms that eat the primary producers are called primary consumers. Primary consumers are usually herbivores (plant-eaters), though they may be algae or bacteria eaters. The organisms that eat the primary consumers are called secondary consumers. Secondary consumers are generally meat-eaters (carnivores).

Detailed explanation-2: -Scientists distinguish between several kinds of consumers. 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-3: -Animals that eat both producers and consumers are called omnivores.

Detailed explanation-4: -Primary Consumer-Animals that consume only plant matter. They are herbivores-eg rabbits, caterpillars, cows, sheep, and deer. Secondary Consumer-Animals that eat primary consumers (herbivores). Tertiary Consumer-Animals that eat secondary consumers ie carnivores that feed on other carnivores.

Detailed explanation-5: -Nectavores consume plant nectar, frugivore consumes fruiting bodies of plants, granivores feed on seeds and grains, folivores consume leaf material, while fungivores eat heterotrophic fungi such as mushrooms.
