Plains are biomes dominated by by tiny to midlarge sessile organisms, usually autotrophs. They are a step in between deserts and forests in amount of precipitation. The list of Plains biomes is unfinished.
occurs: on the sides of mountains
resources: rainfall, snowmelt
elevation: Approximately 5000 feet upwards - relative to latitude.
climate: high temperatures are up to 10 C. great temperature variation between day and night
topography: sloped ground, poor soil
secession stage: 2
autotroph niches: carnivores and herbivores up to midsize
heterotroph niches:up to midsize. (small trees/shrubs are included.)
other: All organizms must be adapted to a thinner atmosphere, meaning less oxygen. High winds probable.
