Trophic level - Wikipedia
WEBThe 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 producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, …
Food web - Wikipedia
WEBThe trophic level is equal to one more than the chain length, which is the number of links connecting to the base. The base of the food chain (primary producers or detritivores) is set at zero. Ecologists identify feeding relations and organize species into trophic species through extensive gut content analysis of different species. The ...
Soil food web - Wikipedia
WEBThe phrase, trophic level, refers to the different levels or steps in the energy pathway. In other words, the producers, consumers, and decomposers are the main trophic levels. This chain of energy transferring from one species to another can continue several more times, but eventually ends.
Ecosystem - Trophic Levels, Food Chains, Interactions
WEBEcosystem - Trophic Levels, Food Chains, Interactions: Together, the autotrophs and heterotrophs form various trophic (feeding) levels in the ecosystem: the producer level (which is made up of autotrophs), the primary consumer level (which is composed of those organisms that feed on producers), the secondary consumer level (which is composed of ...
Food chains & food webs (article) | Ecology | Khan Academy
WEBIn a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain. Food webs consist of many interconnected food chains and are more realistic representation of consumption relationships in ecosystems.
Trophic levels review (article) | Ecosystem | Khan Academy
WEBEach of the categories above is called a trophic level, and it reflects how many consumption steps separate an organism from the food chain's original energy source, such as light. However, in most ecosystems, energy flow is much more complicated than a …

WEBLearn More. 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 - Simple English Wikipedia, the free encyclopedia
WEBTrophic level. Trophic levels categorize organisms into different levels of the food chain. The first trophic level are producers, or autotrophs . Category: Ecology.
Energy flow and primary productivity (article) | Khan Academy
WEBEnergy pyramids. Energy pyramids represent energy flow through trophic levels. For instance, the pyramid below shows gross productivity for each trophic level in the Silver Springs ecosystem. An energy pyramid usually shows rates of energy flow through trophic levels, not absolute amounts of energy stored.
Trophic Level - Definition and Examples | Biology Dictionary
WEBMar 27, 2019 · Trophic Level Definition. 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 …
