Intro Ecology Flashcards
Ecology definition
- how organisms interact w/ each other / environment
Distribution definition
Where organisms found
Abundance definition
How many organisms in given area
What type of distribution is more understood , local/ global
Global
What are barriers to distribution? (2)
Types? (1)
- Physical / climate
- prevent dispersal individuals from place birth to new reproductive site
Distribution/ abundance is affected by both _____ and ______ factors
Explain
- affected by abiotic factors (range of tolerance —-> diff pattern of distribution)
- biotic ( presence other organisms)
Levels of ecology (4)
Individuals
Population
Community
Ecosystem
Organismal ecology def (2)
- how individuals interact environment / each other
- what morphological, behavioral physiological have survive
Population def
Group individuals single species in specific area
Ecology: pop size changes over time? Why? What causing it?
Community def
Assemblage of pop of diff species in specific area
Ecology: types interactions between species? What happens remove species?
Ecosystem def
All organisms in specific region/ abiotic components
Ecology: how energy/ nutrients move through?
