50% OF ALL ANIMAL SPECIES ARE FOUND HERE
INCHES OF RAIN PER YEAR
LOCATED IN THE EQUATORIAL REGIONS OF THE WORLD
MOST DIVERSE PLACE ON EARTH
PROVIDES US WITH WATER VAPOR AND OXYGEN TO OUR ENVIRONMENT

16. MARINE BIOME
Marine region cover about three-fourth of the Earth’s surface.
It includes oceans, coral reefs and estuaries(where salt water and fresh water meet)
It is the largest biome.
The evaporation of the seawater provide precipitation for the land.

18. FRESHWATER BIOME
A freshwater biome is a body of water that contains little salt(less than 1%)
99% of all freshwater is either in the form of ice or located in aquifers.
Freshwater biomes are subdivided into three groups: lakes and ponds, stream and rivers and wetland.
Freshwater biomes are very importan to our survival because they supply people with more than half of their drinking water.
