Detailed explanation-1: -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.

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: -In a food chain, producers or plants make up the first trophic level. The second trophic level is made up of primary consumers or herbivores, third of secondary consumers or carnivores, fourth of tertiary consumers such as animals that feed on other carnivores.

Detailed explanation-4: -The first and lowest level contains the producers, green plants. The plants or their products are consumed by the second-level organisms-the herbivores, or plant eaters. At the third level, primary carnivores, or meat eaters, eat the herbivores; and at the fourth level, secondary carnivores eat the primary carnivores.

Detailed explanation-5: -The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and typically finish with apex predators at level 4 or 5.
