INTERACT WITH
EACH OTHER.
DIFFERENT COMMUNITIES
HABITAT
 DIFFERENT ORGANISMS
REQUIRE DIFFERENT
HABITATS TO MEET
THEIR SPECIFIC NEEDS!
 HABITATS CAN BE USED
BY VARIOUS TYPES OF
ORGANISMS THAT
NEED THE SAME
REQUIREMENTS.
NOT ALL ORGANISMS ARE
ALIKE!!!
Camels: Can go for days
without food or water!
Salamanders: need a
habitat with immediate
access to water
Birds: may need a
habitat with a lot of
trees for building

Fish: saltwater

freshwater habitat
Cactus: may not
need much water
in habitat
ECOSYSTEM
 ALL OF THE
ORGANISMS LIVING IN
AN AREA TOGETHER
WITH THEIR PHYSICAL
ENVIRONMENT.
 COMPOSED OF A
COMMUNITY OF
ORGANISMS LIVING
TOGETHER IN
DIFFERENT HABITATS.
ECOSYSTEM REQUIREMENTS
 ENERGY
 MINERAL NUTRIENTS
(FOR PLANTS AND
ANIMALS)
 WATER (ALL
ORGANISMS)
 OXYGEN (ESSENTIAL
FOR PLANTS AND
ANIMALS)
 LIVING ORGANISMS
(PREDATOR/PREY)
