Movement of energy through the trophic levels of organisms. In most ecosystems, this process begins with photosynthetic autotrophs (plants) and ends with carnivores and detritivores.

The pathway along which food is transferred from trophic level to trophic level, beginning with producers.

Sequence of transfer of matter and energy in the form of food from organism to organism in ascending or descending trophic levels.

The food chain is a sequence of organisms each of which uses the next lower member of the sequence as a food source.

group of organisms linked in order of the food they eat, from producers to consumers, and from prey, predators, scavengers, and decomposers. Read more in the NG Education Encyclopedia

the path of food energy transfer from green plants (primary producers) to grazers (primary consumers), omnivors and carnivores (secondary consumers), and to their predators (top carnivores). The detritus food chain starts when organic matter settles on the ground and breaks down. Because such linear food chains are relatively rare in nature, see Fo [..]

the transfer/flow of energy through an ecosystem. Energy is made available to the system by plants or autotrophs and then moves through the system as each trophic level above feeds on the level below. [..]

A chain of organisms along which energy, in the form of food passes. An organism feeds on the preceding link and is in turn prey for the succeeding link.

a sequence of feeding relationships by which energy is transferred from primary producers to consumers.

The feeding relationships of species that transfer energy through the organisms in a community.

transfer of energy through various stages as a result of feeding patterns of a series of organisms.              

A linked feeding series; in an ecosystem, the sequence of organisms through which energy and materials are transferred, in the form of food, from one trophic level to another.

The chain of trophic relationships formed if several species feed on each other. See food web and trophic level.

a web or series of relationships whereby one organism eats another and is in turn eaten by another; the expression “eating lower on the food chain” means eating fewer animals and more plants

A diagram that shows the flow of food and energy from producers to consumers. The original food source for all organisms in a food chain can be traced to plants. "Food chain" and "food [..]

An abstraction describing the network of feeding relationships in a community as a series of links of trophic levels, such as primary producers, herbivores and primary carnivores

A model that shows how plants and animals are linked together because each one eats or is eaten by another.

A sequence of organisms, each of which uses the next lower member of the sequence as a food source.

a chain of organisms of which each members uses the lower member as a source of food (people eat cows which eat plants). Applebees is at the top of the food chain and McDonalds is at the bottom.

A food chain is the sequence of organisms through which energy and materials are transferred (in the form of food), or the linear progression of feeding levels in which one organism is the food source for the next. (Waller)

The interconnecting links whereby green plants are eaten by animals, which in turn are eaten by other animals.

The sequence of transfer of matter and energy in the form of food from organism to organism in ascending or descending trophic levels (WHO, 1979).

A sequence of organisms, each of which uses the next, lower member of the sequence as a food source. (EPA Glossary)

A sequence of organisms, each of which uses the next, lower member of the sequence as a food source.

A sequence of organisms, each of which uses the next, lower member of the sequence as a food source.

is a sequence of organisms through which energy is transferred from its ultimate source in a green plant; the predator-prey pathway in which organism eats the next link below and is eaten by the link [..]

A sequence of organisms, each of which uses the next, lower member of the sequence as a food source.

The sequence of transfers of matter and energy from organism to organism in the form of Food. Food chains intertwine locally into a Food web because most organisms consume more than one type of Animal [..]

A sequence of organisms, each of which uses the next lower member of the sequence as a food source.

a series of organisms in community in which each organism uses the next, usually lower, member as a food source

The transfer of energy from its primary source (plants) to larger animals.

A linked feeding series; in an ecosystem, the sequence of organisms through which energy and materials are transferred, in the form of food, from one trophic level to another.

A sequence of steps through which food and energy move through the environment from the primary source (plants), through the animals that consume plants, up to the animals which consume other animals.

A graphical representation of the sequence of organisms, each of which uses the next, lower member of the sequence, as a food source. The chain starts with plants or other autotrophs (an organism that [..]

A sequence of organisms, each of which uses the next, lower member of the sequence as a food source.

a succession of organisms in a community that constitute a feeding order in which food energy is transferred from one organism to another as each consumes a lower member and in turn is preyed upon by a higher member.

the pathway of energy transfer through various stages as a result of the feeding patterns of a series of organisms

(food webs, food networks and/or trophic networks) - the feeding relationships between species within an ecosystem.

The succession of populations through which energy flow in an ecosystem as a result of consumer - consumed relationships.

 the transfer of nutrients, and hence energy, from one group of organisms to another in a series or "chain". food web:

A linear sequence representing the direct pathway and nutrition of various species from primary producers (plants) to consumers (top carnivores).

a sequence of organisms from photosynthetic plants to top carnivores through a few intermediary organisms, through which energy and nutrients move within an ecosystem, transferred from one living organism to another, beginning with photosynthesis – ending with consumption and, ultimately, decomposition.

"The transfer of energy from the source in plants trhough a series of organismswith repeated eating and being eaten. At each transfer, a large proportion of the potential energy is lost as he [..]
