What are the levels of ecological organization?
Organism -> Population -> Community -> Ecosystem -> Biome -> Biosphere
All living things
Biotic factors
the number and variety of species within an ecosystem
Species diversity
non-living things
Abiotic factors
sun provides energy
radiation
radiation warms the Earth’s surface
temperature
presence of gases – O2,
CO2, N2 and water vapor
atmosphere
caused by the differences in
temperature and rainfall, disperses pollen and seeds; produces water current
wind
required for all of life
water
quality of soil in an area
influences the kinds of plants that grow
there.)
soil
temperature, sunlight,
atmosphere/precipitation are important
components of a climate
climate
ability of the ecosystem to support
organisms
Carrying capacity
anything that limits the survival of organism
Limiting factor
range of values that is needed for
organism survival
Tolerance range
ideal range
Optimum range
movement of animals into an ecosystem
Immigration
