Detailed explanation-1: -A trophic level is each of the sequential, hierarchical levels in a food chain which is comprised of organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy: Primary producer (green plants) trophic level. Primary consumer (herbivores) trophic level.
Detailed explanation-2: -Organisms in food webs are grouped into categories called trophic levels. Roughly speaking, these levels are divided into producers (first trophic level), consumers, and decomposers (last trophic level).
Detailed explanation-3: -The trophic levels are the positions of organisms on a food chain. They represents a step wise transfer of energy through food, in an ecosystem. The lowest level of a trophic level is occupied by producers. Producers are consumed by primary consumers i.e herbivores and they occupy the second trophic level.
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.
