3. Biomes Each biome is defined by a unique set of abiotic factors.
Particularly climate
A diverse group of plants and animals

4. Biomes
Biome
A large group of ecosystems that shares the same type of climax community.
Terrestrial biomes are located on land.
Aquatic biomes are located in bodies of water.

5. Aquatic Biomes Water makes up the largest part of the biosphere
It covers approximately 75% of the Earth’s surface.
The aquatic biome can be broken down into two basic regions:
Freshwater
Marine

6. Freshwater Biome Freshwater Biome Has low salt concentration
Usually less than 1%
Examples:
Ponds and lakes
Streams and rivers
Wetlands

7. Marine Biome Marine Biome Covers about ¾ of the Earth’s surface
Includes:
Oceans
Coral reefs
Estuaries

8. Terrestrial Biomes Terrestrial biomes vary greatly
Climate is a group of abiotic factors
Influences the type of climax community that develops in the area
The most common terrestrial biomes are:
Tundra
Taiga
Desert
Savannah
Temperate forests
Tropical rainforests

9. Biomes Definitions Tundra- has a layer of permanently frozen soil
Taiga- exists only in northern hemisphere; exhibits coniferous forests
Desert- dry ecosystem with porous soil; home to cacti
Savannah- plants include variety of grasses; home to lions
Temperate Forest- animals such as chipmunks, bears and bats hibernate in the winter

10. Biomes Definitions
Tropical Rain Forest- home to many insects with precipitation year-round
Estuaries- area where freshwater and saltwater mix
Lake- standing body of water with low salinity
Wetlands- thin layer of water that covers the soil; birds use it for nesting and feeding
Oceans- covers the largest part of the biosphere
