How To Determine The Trophic Level Draw a terrestrial food chain that includes four trophic levels. identify the trophic level of each organism in the food chain. this page titled 6.5: trophic levels is shared under a ck 12 license and was authored, remixed, and or curated by ck 12 foundation via source content that was edited to the style and standards of the libretexts platform. 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.
Trophic Level Definition Examples Facts Britannica The trophic levels refer to the position of a group of organisms in the food chain, food web, or ecological pyramid based on their feeding pattern. they are shown in a series or a succession to represent energy flow from one tropic level to another. the position of the trophic level depends upon the number of steps the organism takes from the. 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. The trophic level of an organism is the position it occupies in a food web. within 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. a food web starts at trophic level 1 with primary. Energy transfer and the 10 percent rule. not all food chains and food webs consist of five trophic levels. however, five is the maximum number of trophic levels most ecosystems can support. this is because of inefficiencies in energy flow, which begin with photosynthesis. of all the solar energy that reaches earth, only a small percentage lands.

The trophic level of an organism is the number of steps the organism is from the beginning of the chain. the trophic level helps determine the nutritional relationship between the organism and the primary source of energy. the primary source of energy in any food chain is the sun, except in the case of some deep sea ecosystems.
