1. FOOD
CHAIN

2. What is Food Chain?

3. • All living things depend on each other to live. The
Food chain shows how some animals eat other
animals to survive. While being food for animals
higher in the food chain, these animals may eat
other animals or plants to survive. The food chain
is a complex balance of life. If one animals source
of food disappears, such as from over fishing or
hunting, many other animals in the food chain
are impacted and may die.

4. Food chain is a a transfer of
energy in a sequence of organisms.
It started with the producers to be
consume by consumers eventually
decomposition.

5. • Food chain vary in length from three
to six or more levels. Producers, such
as plants, are organisms that utilize
solar energy or heat energy to
synthesize starch. All food chains
must start with a producer.
Consumers are organisms that eat
other organisms. All organisms in a
food chain, except the first organism,
are consumers.

6. All living organisms on earth will eventually
die. Many plants naturally complete
their life cycle and die within a year.
Decomposers has something to do in the
remains of dead organisms.

7. Plants are so called producers
because they are the only living
things that convert the light energy
(coming from the sun) into chemical
energy. They can produce their own food
through the
process of
Photosynthesis. They are
called
primary producers.

8. Photosynthesis is the process of food
making of plant. They use light water and
carbon dioxide to produce sugar or
glucose.

9. Consumers…………

10. Primary consumers are plant eaters or
herbivores.
Secondary consumers eat primary
consumer. Carnivores eat other animals
and omnivores eat both plants and animals.
Tertiary consumers eat secondary
consumers.

11. Decomposers
are organisms that
break down dead or
decaying
organisms, and in
doing so carry out the
natural process of
decomposition.

12. Food is a
substance from
animals or.
plants which
contains
vitamins and
nutrients that
we need to
survive.

13. The nearer you in the producers the more
energy you will get. That’s why it is
advisable to eat plants and vegetables.
