Detailed explanation-2: -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.
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. This is called the 10 percent rule.

In a food chain, herbivores secures the second trophic level and the food chain as the primary level is always occupied by autotrophs.
