Habitat Notes
Species Interbreed and produce fertile
offspring
Hybrid Interbreed but do not produce
fertile offspring
Population Group of organism in an area
Biological Community Groups of different interacting
organisms (plants and animals) in an area.
Ecosystem Ecologic System
A community of organism Energy and nutrient processing
system Has inputs and outputs Dynamic
Habitat Where an organism lives
Ecological Niche Your functional role (your job) in the ecosystem How you fit in, what you eat, what
eats you, your tolerances Relationships with the environment
Generalist Species eats anything, can live anywhere
Rats, Weeds
Specialist Species picky eater, fragile
Koala
Competitive Exclusion Principle If two or more species coexist
using a limited resources, one will be displaced. Rats & mice Grass & weeds Humans & just about everything
else
Biotic Components Living factors
surrounding plants and animals decomposers
Abiotic Components Nonliving Factors
temp, salinity, sunlight, pH, wind, soil, moisture, gases, time
Biomes Major regional ecological community It is characterized by a distinct climate
and therefore a particular set of plants and animals that have adapted to it. Tundra, Taiga, Temperate Deciduous
Forest, Grassland and Desert Tropical Rain Forest
Aquatic Life Zones Aquatic equal of biome
Marine Coral reefs, estuaries, deep ocean con’t shelf
Freshwater Lakes, rivers, ponds, marshes
Biosphere Earth Biome or Earth Biological
System or Global Biome Skin of life on the Earth bottom of ocean to top of highest mountains
Intersection of the atmosphere, hydrosphere and lithosphere
Closed (materials) System Nutrients, O2, CO2,
Tolerances Temperature Sunlight Acidity of soil Air Pressure Pollution
Range of Tolerances Optimum Range
Range of conditions that an organism is well adapted
Stress Zone Conditions for survival and
reproduction are possible but not optional
Intolerance Zone Conditions for survival are not
possible
Tolerances Different species have widely different
ranges of tolerances. Cockroach, rat
Tolerances
Limiting Factors The factor that is in short supply
and therefore limits the population size. Sunlight in lake, water in desert,
food, Nutrients, Oxygen
