Trophic Level Definition And Examples Biology Online Dictionary

Trophic Level Definition And Examples Biology Online Dictionary A trophic level is the group of organisms within an ecosystem which occupy the same level in a food chain. there are five main trophic levels within a food chain, each of which differs in its nutritional relationship with the primary energy source. the primary energy source in any ecosystem is the sun (although there are exceptions in deep sea. A trophic level refers to a level or a position in a food chain, a food web, or an ecological pyramid. it is occupied by a group of organisms that have a similar feeding mode. in an ecological pyramid, the various trophic levels are primary producers (at the base), consumers (primary, secondary, tertiary, etc.), and predators (apex).

Trophic Level Definition And Examples Biology Dictionary Trophic. definition. adjective. (1) of, relating to, or pertaining to nutrition. (2) of, or involving, the feeding habits or food relationship of different organism s in a food chain. supplement. word origin: greek trophikos. related terms:. The meaning of trophic level is one of the hierarchical strata of a food web characterized by organisms which are the same number of steps removed from the primary producers. Trophic level, any step in a nutritive series, or food chain, of an ecosystem. organisms are classified into levels on the basis of their feeding behavior. the lowest level contains the producers, green plants, which are consumed by second level organisms, herbivores, which, in turn, are consumed by carnivores. Examples of organisms and food chains. single celled organisms known as phytoplankton supply food for small shrimp known as krill in one marine food chain. the blue whale, which is on the third trophic level, feeds primarily on krill. figure 5: food chain example 1 mentioned above.

Simply speaking, the trophic level of an organism is the number of steps it is from the point when the food chain begins. a food chain begins at trophic level 1 which involves primary producers. then it moves on to level 2 which consists of the herbivorous. from then on, the food chain continues to level 3 of the carnivorous organisms. Example 1. pot marigold (calendula officinalis) > european honey bee (apis mellifera) > european bee eater (merops apiaster) > red fox (vulpes vulpes) in this example of trophic levels in a terrestrial food chain, the marigold is the producing organism. the bee only feeds on the pollen and nectar of the flower.
