What is a trophic level?

उत्तर
Trophic levels are the feeding positions of organisms within a food chain, with producers at the base, followed by herbivores and successive levels of carnivores. Each level represents a stage in the transfer of energy and food. An organism can occupy multiple trophic levels depending on what it eats.
