2. Definition
Biomes are similar kinds of ecosystems
found around the world; biomes are
characterized by their physical conditions
(abiotic factors e.g. rainfall and
temperature throughout the year) and the
communities of organisms that interact in
these conditions.

12. Effects of Evaporation
Ratio between Precipitation (P) & Evaporation (E)
• P>E → Increase leaching and loss of nutrients
• P<E → Increase in salinity
