ENVIRONMENTAL SCIENCE
ORGANISM
 ANY LIVING
THING!
-PLANT
-ANIMAL
-FUNGI
-MICROORGANISM
POPULATION
 ALL THE SAME
MEMBERS OF
THE SAME
SPECIES THAT
LIVE IN THE
SAME PLACE
AT THE SAME
TIME
SPECIES
 A GROUP OF
ORGANISMS
THAT ARE VERY
CLOSELY
Mule: male donkey,
RELATED AND and female horse
CAN MATE TO
PRODUCE
FERTILE
OFFSPRING.
Liger: male lion
and female tiger
Zorse: male zebra,
and female horse
COMMUNITY
 A GROUP OF
VARIOUS
SPECIES OR
POPULATIONS
THAT LIVE IN
THE SAME
PLACE AND
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
nests
Fish: saltwater
habitat, or
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)
