what is a population?
multiple individuals of the same species in a small area/time with the potential to interact

what is ecology
- the scientific study of the interaction between living things and their environment
- environment includes things that are biotic (living) and abiotic (nonliving)
what are the levels of ecological research?
- Organismal ecology
- population ecology
- community ecology
- ecosystem ecology
- landscape ecology
- global ecology
what is organismal ecology?
the adaptions of individuals to environment natural history
what is population ecology?
trends in number of individuals and why
what is community ecology?
the effect of interaction between species, focus on biodiversity
what is ecosystem ecology?
the exchange of materials or energy between living and nonliving things
what is landscape ecology?
the shape and arrangement of ecosystems and the effect on how things function
what is global ecology?
the planetary effect on life
what is climate?
