1. FOOD CHAIN

2. Food chain Every living thing needs
energy in order to live.
Everytime animals do
something (run, jump)
they use energy to do
so.
Animals get energy from
the food they eat, and
all living things get
energy from food. Plants
use sunlight, water and
nutrients to get energy
(in a process called
photosynthesis). Energy
is necessary for living
beings to grow.

3. Herbivores and Carnivores

4. Omnivores
Some animals eat
both plants and
animals. They are
omnivores.
Omnivores include
mammals like grizzly
bears, striped skunks
and raccoons and
birds like crows, blue
jays and
woodpeckers.

5. Photosynthesis
Photosynthesis - The
cycle of plants and
how they make energy!
The sun(light energy),
water, minerals and
carbon dioxide are all
absorbed by the plant.
The plant then uses
them to make
glucose/sugar, which
is the energy/food for
the plant.

6. Decomposers
Fungi and bacteria
play an important
role in nature. They
break down the
unused dead
material and turn
them into nutrients
in the soil, which
plants use to grow.
They are an
important part of
the food chain.

7. FOOD WEB
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.
