Detailed explanation-1: -The position, level, or position in a food web, a food chain, or an ecological pyramid is known as a trophic level. The first trophic level is formed by the producers, as they produce food. The second trophic level is formed by the primary consumers. The third trophic level is formed by the secondary consumers.

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: -trophic level, step in a nutritive series, or food chain, of an ecosystem. The organisms of a chain are classified into these levels on the basis of their feeding behaviour. The first and lowest level contains the producers, green plants.

Detailed explanation-4: -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-5: -All food chains and webs have at least two or three trophic levels. Generally, there are a maximum of four trophic levels. Many consumers feed at more than one trophic level. Humans, for example, are primary consumers when they eat plants such as vegetables.
