FOOD CHAIN
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.
Herbivores and Carnivores
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 .
