Food chains and food webs and/or food
networks describe the feeding relationships
between species in a biotic community.
In other words, they show the transfer of
material and energy from one species to
another within an ecosystem.
As usually put, an organism is connected to
another organism for which it is a source of
food energy and material by an arrow
representing the direction of biomass
transfer.
Organisms are grouped into trophic levels
based on how many links they are removed
from the primary producers.
Primary producers, or autotrophs, are
species capable of producing complex
organic substances (essentially "food") from
an energy source and inorganic materials.
These organisms are typically
photosynthetic plants, bacteria or algae, but
in rare cases, like those organisms forming
the base of deep-sea vent food webs, can
be chemotrophic.
All organisms that eat the autotrophs are
called heterotrophs.
They get their energy by eating the
producers.
A food chain describes a single pathway
that energy and nutrients may follow in an
ecosystem.
There is one organism per trophic level, and
trophic levels are therefore easily defined.
