ECOLOGY Introduction
Ecology is about Cause and Effect Looks at the
Interaction & InterdependenceOf organisms to each other and to their
environment. We have studied
Genus and species populations
Expanding outward to…
ECOLOGY “ECO” – “the Environment” /”nature” “OLOGY”- study of
The study of the interactions between organisms within a particular area.
Ecology vocabulary words:Individual – single organism.Population – group of individuals who can
mate (species).Community – Groups of different
populations within a particular area.Ecosystem – Living and non-living
things within a particular area.Biome – Groups of similar ecosystems
living together.Biosphere – THE WHOLE WORLD
EcosystemSelf-sustaining collection of organisms and their physical environment
Biotic – living thingsAbiotic – non-living things
BiomeMajor communities that occur over wide areas on land
Scientists have divided the Earth into 7-9 major biomes
Climate – temperature and precipitation.
Climate dictates biomes.
Major Biomes of the Earth
Niche-Animal’s role in the ecosystem. Types of niches: HerbivoreOmnivoreCarnivore
PredatorPrey
DecomposerScavenger
PRIMARY PRODUCERS
In your groups define using two to three words
Food Chains
Eats ProducersEats consumers and producersEats only live animals.
The hunterThe hunted
Break down dead and organic materialEats animals that are dead/ have been killed
FOOD CHAIN SETS:In your group Put your groups set in order
Check another groups set
Draw one of the food chains!
THE ARROW IN A FOOD WEB SHOWS WHERE THE ENERGY GOES TO!!
Arrows on the food web show where the energy goes.
Various Relationships Mutualism
Neutralism
Competition & Predation
Commensalism
Parasitism
Both organisms benefit
Neither organism benefits
One organism out runs another or takes over an area
One benefits, nothing happens to the other.
Host does not benefit, ONLY parasite does
Match the situation to one of the relationships
