organism distribution

what mainly shapes terrestrial biomes?

temperature + precipitation

macroclimate + local landscape creates what

microclimate

why can microclimate affect species distribution

organisms experience local conditions

what shapes aquatic organism distribution

physical + chemical conditions

what aquatic conditions change with depth

light, temp, O2

why is light ecologically important in water

limits photosynthesis

what 3 features identify terrestrial biomes?

climate, soil, dominant plants

how does vegetation affect microclimate

shade changes local temperature

kelp forests occur where

temperate subpolar waters

coral reefs occur where

near equation less than/equal to 30 degrees

estuary

where rivers meet seas

salt marshes occur where

temperate high latitudes

mangroves occur where

tropical/subtropical regions

ocean light with depth

decreases

euphotic zone

sunlit, photosynthesis occurs

river structure dimensions

length, width, depth

thermocline

rapid temperature change with depth

lake stratification affects what

temperature, o2, nutrients
