BiomesMegan Gardner, Dianna Cardenas,

Aquatic Biomes• Freshwater: low salt concentration • Ponds and Lakes: range in size, limited

species• Streams and Rivers: bodies of flowing

water moving in one direction • Wetlands: highly diverse in species, salt

marshes are wetlands but they are not a freshwater region

Marine Biomes• Oceans

o Intertidal: ocean meets lando Pelagic: open ocean away from lando Benthic: below pelagic zoneo Abyssal: the deepest parts of the ocean

• Coral Reefs: warm, clear, shallow waters near coastlines

Deserts • Dry areas where

evaporation usually exceeds precipitation

• Hot deserts: hot in the summer, seasonal rainfall

• Cold deserts: cold winters low year round precipitation

• Semiarid deserts: transition between deserts and grassland

Grassland • Moderate rainfall is

sufficient for the growth of grass

• Tropical grasslands (savannas): warm climates, scattered trees

• Temperate grasslands (prairies): short grass, treeless

Forests • Tropical: warm, wet, lower latitudes,

precipitation is high, high biodiversity • Temperate: mid latitudes, summers are

warm and winters are cold• Boreal (taiga): higher latitudes, long cold

winters, short summers

Tundra• Low vegetation,

precipitation, biodiversity

• Artic: polar regions, short summer growing season.

• Alpine: high elevation, longer summers

Quiz • How many different types of biomes

are there?• What is intertidal? Give an example.• What is the difference between

savannas and prairies?
