Ecology's Levels of Organization
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Ecology studies interactions among organisms and their environment across nested levels: organism, population, community, ecosystem, and biosphere.
Show
A single oak tree is an organism; every oak of its species in a forest is a population; every species sharing that forest is a community.
Watch for
A "population" in ecology means one species' individuals in one area, never a mixed group of different species.
Builds on
- Nothing — this is a starting point.
