Download Food chain and food web


A carnivore is an animal
that gets food from killing
carnivores have to hunt
down and kill other
animals they require a
large amount of calories.
This means that they
have to eat many other
animals over the course
of the year. The bigger
the carnivore, the more it
has to eat. You should
make sure that you have
many more herbivores
and omnivores than
carnivores.ling and
eating other animals

A herbivore is an
animal that gets its
energy from eating
plants, and only
plants. Omnivores
can also eat parts of
plants, but generally
only the fruits and
vegetables
produced by fruitbearing plants.
Many herbivores
have special
digestive systems
that let them digest
all kinds of plants,
including grasses.

An omnivore is a
kind of animal that
eats either other
animals or plants.
Some omnivores will
hunt and eat their
food, like
carnivores, eating
herbivores and
other omnivores.
Some others are
scavengers and will
eat dead matter.
Many will eat eggs
from other animals.

An organism that feeds on
and breaks down dead plant
or animal matter, returning
essential nutrients to the
ecosystem. Detritivores
include microorganisms such
as bacteria and protists as
well as larger organisms such
as fungi, insects, worms, and
isopod crustaceans. In a
food chain, detritivores are
primary consumers

A food chain shows the
feeding relationship
between different living
things in a particular
environment or habitat.
Often, a plant will begin a
food chain because it can
make its own food using
energy from the sun. Also, a
food chain represents a
series of events in which
food and energy are
transferred from one
organism in an ecosystem
to another. Food chains
show how energy is passed
from the sun to producers,
from producers to
consumers, and from
consumers to decomposers.
In a food chain each
organism obtains energy
from the one at the level
below.
 Plants are called producers
because they create their
own food through
photosynthesis3
 Animals are consumers
because they cannot create
their own food, they must eat
plants or other animals to get
the energy that they need.


A food web is a
diagram of the
links among
species in an
ecosystem –
essentially who
eats what. A
food chain
shows only the
organisms that
contribute to
the diet of the
top consumer.
The base of a food web is occupied
mostly by vegetation (producers) and
fine organic debris (decomposers).
 Herbivores (primary consumers) and
carnivores (secondary consumers)
occupy the higher levels.
 Omnivores occupy an intermediate level
in the food web.
 Food webs are complicated by the fact
that many species feed at various levels.

FOOD CHAINS FOLLOW A SINGLE PATH
AS ANIMALS EAT EACH OTHER.
FOOD WEBS SHOW HOW PLANTS &
ANIMALS ARE INTERCONNECTED BY
DIFFERENT PATHS.
A food chain only shows one food
relationship of a biotic element.
A food web only shows the orca eating
a ringed seal.
A food chain shows how each living
thing gets its food.
A food web is a series of related food
chains displaying the movement of
energy and matter through an
ecosystem.

This is because plants the only autotrophs
on earth (meaning the only ones who
can prepare there own food) prepare
their food by a process called
photosynthesis for which sunlight is an
important component and as we know
all living beings directly or indirect
depend on plants for their food thus sun
is very important for the food chain

Algae, a microrganism (a tiny
organism) serves as food for
small aquantic creatures such
as krill and shrimp, and these
small organisms serve as food
for larger animals such as
whales and manitees. Basically,
algae serves as food for small
animals, and these animals
serve as food for large animals,
which keeps the food chain
balanced, with the provider, in
this case the algae, at the
bottom, and the primary
(manitees) and secondary
(whales) consumers are at the
middle and the top.

Food chains and webs ensure that one particular
species cannot become too large and therefore
destroy the species it feeds on, creating a massive
inbalance. This means that every creature has a
predator and/or environmental threats so their
population cannot increase to an amount that is
unhealthy for the surounding ecosystem.
