Biogeography and Abiotic Distribution Factors
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Biogeography studies how abiotic factors — temperature, water, light, and soil nutrients — shape where species are geographically distributed.
Show
Traveling from the equator toward the poles crosses tropical forest, desert, grassland, and tundra in a sequence abiotic gradients predict.
Watch for
A species' range reflects abiotic tolerance and biotic interaction together — neither factor alone fully explains a distribution.
