Six levels
Species, population, community, eco-system, biome, biosphere
observation
to watch what goes on in an environment
experimenting
In a lab, so you don't harm the environment, set up an eco-system to test.
modeling
creating a replica of something in the environment
Abiotic
non living organisms in an environment
Biotic
living organisms in an environment
Habitat
Where organisms live
Niche
The part organisms play in a habitat
Preditor/prey relationship
Short term relationship, preditor kills and eats prey.
Symbiosis
any long term or close personal relaionship between 2 species
Commensalism
One organism is benifited and one dies.
mutualism
both organisms are benefitted
parasitism
one organism is benifited andone is unfazed
Interspecies competition
competition between different species
intraspecies competition
competition between organisms of the same species
Limiting factors
limits how large a factor can grow. Biotic or ABiotic
producers
Autotrouve. Converts solar energy into food energy
Consumers
Eat producers to get energy.
Herbivors
Primaryconsumer. They only eat plants.
Carlivores

Scavengers
feed off dead orgaqnisms they did not kill
Primary consumers
Eat the consumers eat the producers
secondary consumers
only eat other producers
Decomposers
They break down dead organisms and take in some nutrients and release some in the soil.
Enerygy pyramids
Shows the amount of energy passed on.
Food webs
Represents relationships in an eco-system.
Carrying capacity
Number of organisms that carry support
Ecological succesion
one community replaces another to maintain a forming new stable organisms
Pioneer community
First community to enter and survive in a destroyed eco-system.
Climax community
No longer going through succession. Stable. Lots of biodiversity
