ECOLOGY
Definition
THE SCIENTIFIC STUDY OF INTERACTIONS AMONG ORGANISMS AND BETWEEN ORGANISMS AND THEIR ENVIRONMENT, OR SURRONDINGS
Term
BIOSPHERE
Definition
CONTAINS THE COMBINED PORTIONS OF THE PLANET IN WHICH ALL OF LIFE EXIST INCLUDING LAND, WATER, AND AIR OR ATMOSPHERE
Term
SPECIES
Definition
A GROUP OF ORGANISMS SO SIMILAR TO ONE ANOTHER THAT THEY CAN BREED AND PRODUCE FERTILE OFFSPRING
Term
POPULATIONS
Definition
GROUP OF INDIVIDUALS THAT BELONG TO THE SAME SPECIES AND LIVE IN THE SAME AREA.
Term
COMMUNITIES
Definition
ASSEMBLYS OF DIFFERENT POPULATIONS THAT LIVE TOGETHER IN A DEFINED AREA
Term
ECOSYSTEMS
Definition
A COLLECTION OF ALL THE ORGANISMS THAT LIVE IN A DEFIND AREA
Term
BLOME
Definition
A GROUP OF ECOSYSTEMS THAT HAVE THE SAME CLIMATE AND SIMILAR DOMINAT COMMUNITIES
Term
ECOLOGICAL METHODS
Definition
REGARDLESS OF THE TOOLS THEY USE SCIENTIST CONDUCT MODERN ECOLOGIST RESEARCH USING THREE BASIC APPROACHES: OBSERVING ,EXPERIMENTING, AND MODELING . ALL OF THESE APPROACHES RELY ON THE APPLICATIONS OF SCIENTIFIC METHODS TO GUIDE ECOLOGICAL INQUIRY
Term
ECO METHODS CONTINUE
Definition
OBSERVING IS OFTEN THE FIRST STEP IN ASKING ECOLOGIST QUESTIONS. SOME OBSERVATIONS ARE A LITTLE BIT MORE DIFFICULT THAN OTHERS

ENERGY FLOW
Definition
(ENERGY IS NEEDED TO POWER EVERYTHING IN LIFE. SUNLIGHT IS THE MAIN ENERGY FOR LIFE ON EARTH) PRODUCES ORGANISMS THAT MAKE THEIR OWN FOOD..
Term
PLANTS
Definition
THEY USE ENERGY FROM THE SUN TO MAKE FOOD THIS IS (PHOTOSYNTHESIS)CONSUMERS
Term
ORGANISMS
Definition
GET ENERGY FROM OTHER ORGANISMS
Term
EXPERIMENTING
Definition
EXPERIMENTS CAN BE USED TO TEST HYPOTHESIS
Term
MODELING
Definition
ECOLOGIST MAKE MODELS TO GAIN INSIGHT INTO COMPLEX PHENOMINA SUCH AS THE EFFECTS OF GLOBAL WARMING ON ECOSYSTEMS
Term
ECOLOGICAL MODELS
Definition
CONSIST OF MATHEMATICAL FORMULAS LOSED ON DATA COLLECTED THROUGH OBSERVASTIONS AND EXPERIMENTATIONS
Term
PREDICTIONS
Definition
ONE OFTEN TESTED BY FURTHER OBSERVATIONS AND EXPERIMENTS
Term
CONSUMERS
Definition
GET ENERGY FROM OTHER ORGANISMS
Term
THREE TYPES OF CONSUMERS
Definition
HERBIVORS (EAT PLANTS)>>>
CARNIVORS (EAT ANIMALS)>>>
OMNIVORES (EAT PLANTS AND ANIMALS)>>>
Term
DECOMPOSERS
Definition
-THREE BREAK DOWN ORGANIC MATTER
ENERGY FLOWS IN AN ECOSYSTEM
ENERGY FLOWS IN ONE DIRECTION
ENERGY STORED BY PRODUCERS IS PASSED IN A FOOD CHAIN TO CONSUMERS
