Types of Organisms
Its all about what you eat!
An organism is …..
Any independent
living thing
Can be as small
as a
single celled
bacteria
Or as large as a
whale!
The three categories of the
organisms are…..
1) Producers
2) Decomposers
3) Consumers
They are all dependent on each
other.
Producers/AutotrophsProducers use energy
from sun to make their
own food through
photosynthesis.
EX: plants- flowers, trees, grass
DecomposersDecomposers break
down dead things
and return them to
the dirt, or soil.
YUCK!
Examples:
Mushrooms
Worms
Bugs
Bacteria
Consumers/HeterotrophConsumers need
to eat food to get
energy.
(ANIMALS)
.
There are THREE types of Consumers:
Carnivores
Herbivores
Omnivores.
Its still all about what you eat!
Carnivores only eat meat
(other animals)
Herbivores- eat only plants
Examples- giraffe, rabbit, cow,
squirrel, deer
Omnivores- eat both
meat (animals) and plants.
Examples- bears, pigs, humans
Scavengers
Scavengers -animals that feed on dead or
injured animals.
Scavengers are not usually held in high esteem,
but they have a job to do: they clean the earth of
organic garbage.
Carrion, a favorite treat of scavengers, is the
flesh of dead and rotting animals.
Examples- cockroaches, vultures, buzzards,
jackals, & raccoons
