===About Food Chains===
: A '''food chain''' always begins with a [[producer]] which is a creature that makes its own food, like [[plant]].
: The [[producer]] in a '''food chain''' is always eaten by a [[consumer]].
: The arrows in a '''food chain''' always point from the food to the animal that eats it.

===Meaning===
A '''food chain''' is a [[diagram ]] used to show which creatures rely on each other for food the transfer of [[energy]] between [[organism]]s in a [[habitatBiological Community|community]].{{#ev:youtube|https://youtu.be/CkWjaf4MSyQ}}To see the answers to the questions in the video, click here: [https://keystagewiki.com/index.php/File:FoodChainAnswers.png]
===About Food Chains===
: A '''food chain''' always begins with a [[producer]] which is a creature that makes its own food, like [[plant]].
: A '''food chain''' usually ends with a [[Top Carnivore|top carnivore]] which is not eaten by other [[carnivore]]s.
: The arrows in a '''food chain''' always point from the food to the animal that eats it.
: The [[producer]] in a '''food chain''' is always eaten by a [[consumer]].
: With each [[consumer]] the total energy gets smaller. When the primary consumer eats the producer it does not get all the energy because the producer used some of that energy in respiration. When the secondary consumer eats the primary consumer it does not get all the energy because the primary consumer used that energy for movement, it lost some energy in respiration and parts of its body cannot be digested by the secondary consumer.

===About Food Chains===
: A '''food chain''' is split into several [[Trophic Level|trophic levels]].
: The first [[Trophic Level|trophic level]] in '''food chains''' are [[producer]]s which make their own food by [[photosynthesis]].
: The last [[Trophic Level|trophic level]] in a '''food chain''' is usually an [[Apex Predator|apex predator]] which may be a [[Tertiary Consumer|tertiary consumer]] or a [[Quaternary Consumer|quaternary consumer]].
: The arrows in a '''food chain''' always point in the direction of [[energy]] transfer between the [[Trophic Level|trophic levels]].
: The [[producer]] in a '''food chain''' is always eaten by a [[consumer]].
: With each [[consumer]] the total [[energy]] passed to the next [[Trophic Level|trophic level]] is smaller.
: When the [[Primary Consumer|primary consumer]] eats the [[producer]] it does not get all the [[energy]] because the [[producer]] used some of that [[energy]] in [[respiration]]. The [[Primary Consumer|primary consumer]] also cannot [[digestion|digest]] all of the parts of the [[producer]] so some [[energy]] is wasted as [[faeces]].
: When the [[Secondary Consumer|secondary consumer]] eats the [[Primary Consumer|primary consumer]] it does not get all the [[energy]] because the [[Primary Consumer|primary consumer]] used that [[energy]] for movement, it lost some [[energy]] in [[respiration]] and parts of its body cannot be digested by the [[Secondary Consumer|secondary consumer]].
