A food chain is somewhat a linear sequence of links in a food web starting from a trophic species that eats no other species in the web and ends at a trophic species that is eaten by no other species in the web. A food chain differs from a food web, because the complex polyphagous network of feeding relations are aggregated into trophic species and the chain only follows linear monophagous pathways. A common metric used to quantify food web trophic structure is food chain length. In its simplest form, the length of a chain is the number of links between a trophic consumer and the base of the web and the mean chain length of an entire web is the arithmetic average of the lengths of all chains in a food web.
Food chains were first introduced in a book published in 1927 by Charles Elton, which also introduced the food web concept.
Food chains are directional paths of trophic energy or, equivalently, sequences of links that start with basal species, such as producers or fine organic matter, and end with consumer organisms.
You're a part of the food chain
Just a part of the food chain
You're a part of the food chain
Dance until you can't eat no more
You're a part of the food chain
Just a part of the food chain
You're a rotten little part of the food chain
And I can't stand your constant conducting
So keep your
Dress pulled tight over your shaking little body
And just let love feel the pull
So keep your
Head on my shoulder
Because as I get older
I'm finding it harder and harder to believe
So I've been thinking more and more
About my minimum wage life
And it's getting really crazy out there
So why don't you just stay here tonight?
So keep your hands in the air
And just let your heart
Hit the floor
Na Na Na Na Na
No can't catch me
Na Na Na Na Na
Never
So as the summer let's you go
You won't be coming back 'round here
So I think you should know
