Detailed explanation-1: -Trophic level of herbivore : Herbivores are primary consumers as they feed on the producers. Hence, herbivores belong to the second trophic level (T2).

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: -Herbivores are primary consumers, which means they occupy the second trophic level and eat producers. For each trophic level, only about 10 percent of energy passes from one level to the next.

Detailed explanation-4: -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. Tertiary consumers eat the secondary consumers.

Detailed explanation-5: -In a food chain, the consumption of one organism by another occurs in a unidirectional flow. The herbivore consumes autotrophs and the carnivore consumes herbivores. In a food chain, herbivores secures the second trophic level and the food chain as the primary level is always occupied by autotrophs.
