Ecology Part 2Ecosystems

Factors that affect the Biodiversity of an Ecosystem•Weather and Climate•Biotic and Abiotic Factors•Community Interactions•Brainpop—Ecosystems!

Weather and Climate•Weather= Day to day condition of Earth’s atmosphere•Climate= Average conditions of temperature and precipitation of an area•Quickwrite•How do you think climate affects an ecosystem??

Biotic and Abiotic Factors•Biotic Factors—the living components of an

Community Interactions

CompetitionOrganisms compete

for the same resource within an ecosystem

PredationOne organism

captures and feeds on another organism

SymbiosisTwo species live closely together

(mutualism, commensalism,

parasitism)
