Detailed explanation-1: -(a) The consumers that feed on the herbivores are carnivores or more correctly primary carnivores. (b) The detritus food chain (DFC) begin with dead organic matter. (c) Based on the source of nutrition or food, organisms occupy a specific place in the food chain that is known as their trophic level.

Detailed explanation-2: -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: -A horse is a mammal that is a primary consumer. They are herbivores and eat mostly vegetation. Horses are very social animals and live in herds. In the wild, they roam freely and graze on grasses all day long.

Detailed explanation-4: -Primary consumers are always herbivores, or organisms that only eat autotrophic plants. However, secondary consumers can either be carnivores or omnivores. Carnivores only eat other animals, and omnivores eat both plant and animal matter.
