FOOD CHAIN

What is Food Chain?

• 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.

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.

• 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.

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.

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.

Photosynthesis is the process of food

making of plant. They use light water and

carbon dioxide to produce sugar or

glucose.

Consumers…………

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.

Decomposers

are organisms that

break down dead or

decaying

organisms, and in

doing so carry out the

natural process of

decomposition.

.

Food is a

substance from

animals or

plants which

contains

vitamins and

nutrients that

we need to

survive.

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