A food web (or food cycle) is the natural interconnection of food chains and generally a graphical representation (usually an image) of what-eats-what in an ecological community. Another name for food web is a consumer-resource system. Ecologists can broadly lump all life forms into one of two categories called trophic levels: 1) the autotrophs, and 2) the heterotrophs. To maintain their bodies, grow, develop, and to reproduce, autotrophs produce organic matter from inorganic substances, including both minerals and gases such as carbon dioxide. These chemical reactions require energy, which mainly comes from the sun and largely by photosynthesis, although a very small amount comes from hydrothermal vents and hot springs. A gradient exists between trophic levels running from complete autotrophs that obtain their sole source of carbon from the atmosphere, to mixotrophs (such as carnivorous plants) that are autotrophic organisms that partially obtain organic matter from sources other than the atmosphere, and complete heterotrophs that must feed to obtain organic matter. The linkages in a food web illustrate the feeding pathways, such as where heterotrophs obtain organic matter by feeding on autotrophs and other heterotrophs. The food web is a simplified illustration of the various methods of feeding that links an ecosystem into a unified system of exchange. There are different kinds of feeding relations that can be roughly divided into herbivory, carnivory, scavenging and parasitism. Some of the organic matter eaten by heterotrophs, such as sugars, provides energy. Autotrophs and heterotrophs come in all sizes, from microscopic to many tonnes - from cyanobacteria to giant redwoods, and from viruses and bdellovibrio to blue whales.
Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as fats, proteins, vitamins, or minerals. The substance is ingested by an organism and assimilated by the organism's cells to provide energy, maintain life, or stimulate growth.
Historically, people secured food through two methods: hunting and gathering and agriculture. Today, the majority of the food energy required by the ever increasing population of the world is supplied by the food industry.
Food safety and food security are monitored by agencies like the International Association for Food Protection, World Resources Institute, World Food Programme, Food and Agriculture Organization, and International Food Information Council. They address issues such as sustainability, biological diversity, climate change, nutritional economics, population growth, water supply, and access to food.
The right to food is a human right derived from the International Covenant on Economic, Social and Cultural Rights (ICESCR), recognizing the "right to an adequate standard of living, including adequate food," as well as the "fundamental right to be free from hunger."

I came into this world high as a bird
From second hand cocain powder
i know it sounds absurd
I never tooted but its in my veins
While the rest of the country bungies off bridges
Without no snap back
and bitches they say they need that
To shake they fannies in the ass clubs
they go the other route
turn each other out
burn each other out
where a bonified nigga like me
can't even get no back rub these days
ain't that bleak on they part
but let me hold it down
cause they shut you down
when you speak from your heart
now that's hard
while we rantin and ravin bout gats
nigga they made them gats
they got some shit that'll blow out our backs
from where they stay at
Chorus:
Ooooh, I fear the battle's just begun
Ooooh, though we're here someday we will be gone
so i'm hopin, wishin, prayin
to keep my faith in you, in you
(yo, yo, yo in background)
I'm fascinated by the way yo
nipples peak at me through yo blouse
freaky me, freaky you
can't help but be aroused
'scuse me lord less for thinkin
but that's the way we was brought up
sneakin to watch playboy at night
we all must be caught up in worldly ways
Chemistry between boys and girls
is alot like when we went to the woods
and laid with the squirrels
durin P.E., we'd be
exploring each others privates
hunchin with all our clothes on
until we felt excited then, aaaah
oh now its on from here on out
put yo hands in the atmosphere
if you know what i'm talkin bout
now if two hearts done walk on out
and i see you on the next song
they call it horny
Because its devilish
now see we dead wrong
Chorus
People don't know the stress i'm dealing with day to day
Speakin about the feeling i'm possessing for Rene
Mopin around and wondering where she stay
saw her last that she lay
give it another day i say
but the lord he taketh away
now give it back lawd
cause that's like backboards without the rims
me and my auntie was tight like southwest
before the pinks moved in
like the niggas that owned the ligour store
crack cocaine, pimps and whores
livin up on this earth
before a nigga like daddy was born
but they makin a scene
that my music and crime are a team
but i'm speakin the truth not dreams
so what in the fuck they mean
my lyrics ain't clean
Chorus
