FOOD CHAIN

Page 2: Food Chain By Zayed

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.

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.

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.

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

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 .
