NEET BIOLOGY

Detailed explanation-1: -The trophic level of an organism is the position it occupies in a food web. A food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves. The trophic level of an organism is the number of steps it is from the start of the chain.

Detailed explanation-2: -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-3: -Final answer: Functional level (position) occupied by an organism in any food chain is its trophic level.

Detailed explanation-4: -Some food chains have additional levels, such as quaternary consumers-carnivores that eat tertiary consumers. Organisms at the very top of a food chain are called apex consumers.
