| Food
chain |
| A
food chain is a community of organisms where each
member is eaten by another member. The arrows
indicate the way the food chain goes for instance
grass is eaten by a cow and a cow is eaten by a
human and a human is eaten by a mosquito. The
arrows point in a certain way because it shows
the way the food chain gets eaten by. The food
chain is limited because it doesn't show all the
relationships the organisms have. It doesn't show
the big picture because it only shows cetain
organisms and doesn't show all the organisms that
there are. The big picture would be when it shows
all the organisms and what they eat. |

| Food
Webs: |
| A
food Web is a set of interconnected food chains
by which energy and materials circulate within an
ecosystem. The food web is divided into two
groupswhich are the grazing web, which begins
with green plants, algae.or
photosynthesizing plankton, and the detrital web,
which begins with organic debris. These webs are
made up of individualfood chains.In a grazing
web, materials typically pass from plants to
plant eaters (herbivores) to flesh eaters (carnivores).
In a detritialweb, materials pass from plant and
animal matterto bacteriaand fungi (decomposers),
then to detritial feeders (detritivores),and then
to there predators (carnivores). |

| The
Delicate Balance of Organisms: |
| If a speices
starts to die out then the food chain will change
because that animal would of had to eat a
producer and the carnivore would of had to eat
the herbivore so that would mean some of the
carnivores were dying also because there wouldn't
be any food left for them to eat if a herbivore
suddenly died out. When the rainforest starts to
get damaged that means some of the herbivores
will die out because when the rainforest gets
damaged some of the plants are getting damaged
too and that is all some of the herbivores eat
besides fruit. This would effect the food chain
because some of the herbivores would die out as
well as the carinvores that eat that herbivores. |
