Climate and biomes Biomes are major (terrestrial) ecological zones within the biosphere The type of ecosystem that emerges in an areas can be predicted based upon the climate. © 2016 Paul Billiet ODWS

Biomes Determined by climate Characterised by their vegetation type
Arranged broadly by latitude Can also be influenced by oceans, mountain ranges. © 2016 Paul Billiet ODWS

Nutrient flow B Nutrients are recycled in a closed ecosystem
The rate of recycling between the different can be shown on Gersmehl diagrams Arrow thickness = flux Disc size = reservoir B = Biomass L = Litter S = Soil B Rainfall Leaf fall Root absorbance L S Decomposition Surface runoff Leaching Weathering © 2016 Paul Billiet ODWS
