TundraVery coldLow diversitySimple vegetationShort growing season

GrasslandsThere are two types of grasslands. The tropical grasslands (savannah) and the temperate grasslands.

Dominated by gassessavannah has a wet and dry season

Temperate grassland has a hot summer and cold winter

DesertAnimals are smallMany animals are nocturnalTemperatures can be very hot or very cold

Plants are adapted to conserve water

Page 8: biomes.......wild life

Tropical ForestVery rainyLittle variation in climate

Highly diverse speciesSoil is nutrient-poor and acidic

Page 9: biomes.......wild life

Decidious ForestTemperature variesSoil is rich with decayed matterPlants consist of broad leave trees

Includes animals such as squirrels, rabbits, skunks, and bear.

Even precipitation throughout the year

Coniferous ForestAlso called the taiga or boreal forestThe largest terrestrial biomeTemperatures are lowPrecipitation is primarily snowSoil is nutrient poor and acidicFlora is mostly conifersAnimals include woodpeckers,

hawks, moose, bear and lynx.

Marine BiomeConsists of oceans, coral reefs, and

estuariesThe ocean is the largest of all ecosystems.The ocean contains a diverse array of

plants and animals at various depth zones.Coral reefs consist mainly of coral.Estuaries are areas where fresh and salt

water environments converge. Mangroves, oysters, crabs and marsh grasses are examples of species in this environment.

Freshwater BiomesIncludes ponds, and lakes; streams and rivers, and wetlands.

Ponds and lakes have well lit zones and a variety of fish dominate this zone.

Streams and rivers move in one direction.

Wetlands are areas of standing water that support aquatic plants.
