PRODUCERS,
CONSUMERS AND DECOMPOSERS

Fatu Camra 4 A

Producers are organisms that produce organic compounds from inorganic compounds. These are also a type of autotroph. Producers are living things that can make their own food using air, light, soil, and water.

An autotroph is an organism that makes its own food from inorganic substances. It is then eaten by a consumer if it is a plant for example.

PRODUCERS

EXAMPLE

Plants use a process called photosynthesis to make food.Only them can produce their own food.

So they are a very good exmple of producers because they make their own food using sunlight, air, nutrients and water.

CONSUMERS

A consumer is the organisms that obtain nutrients from other organisms. This is also heterotroph.They are organisms that are not able to make their own food so they get already done.Consumers are the next link in a food chain.A heterotroph is an organism that cannot synthesize their own food and must obtian it ready made.

TYPES OF CONSUMERS/HETEROTROPHS

There are three levels of consumers.(but not all the animals are clasified obligatory in them)

It all depends on what the animals eat and how they obtain the food they need. Heterotrophs include herbivores, carnivores, omnivores.

Herbivores or Primary Consumers:They are animals that feed only on plants.Eg:Rabbits, cattle, horses, sheep and deer .

TYPES

-Carnivores or Secondary Consumers:They are animals that feed on other animals.They eat the primary consumers. Some carnivores may be - Predators, such as lions, hawks, and wolves who attack and kill their prey and feed on their bodies. -Scavengers, they feed on dead animals that they find.

TYPES

There are also consumers called omnivores. Omnivores can either be secondary or tertiary consumers

-Omnivores are living beings that feed on both plants and animals.Eg:HUman and bears.

DECOMPOSERS

A decomposer is an organism of decay. These are also known as saprobes. They break down the remaines of dead animals and plants, releasing the substances that can be used by other members of the ecosystem.

Decomposers are an essential component of any ecosystem. Their main role is to recycle nutrients in dead organisms and their wastes.Eg:bacteria and fungi.
