    • Biomes
       A biome is a large ecosystem where plants, animals, insects, and people live in a certain type of climate
    • Kinds of Biomes
      Terrestrial
      Rainforests (Temperate or Tropical)
      Tundra
      Taiga
      Desert
      Temperate Deciduous
      Grassland
      Aquatic
      Marine
      Oceans
      Coral Reefs
      Estuaries
      Freshwater
      Rivers and Streams
      Ponds and lakes
      Wetlands
    • Biome Characteristic: Rainforests
      2 types: Topical and Temperate
      Most trees flare at the base
      Vegetation is dense (tall and green)
      Rich in diversity (especially in tropical rainforests)
      Precipitation and Climate 
      Lush and wet
      Rainfall is regular throughout the year (80-400 inches of rainfall per year for tropical)
      Tropical rainforests are warm and moist; while temperate rainforests are cool. 
    • Biome Characteristic: Tundra
      Arctic tundra is located at the poles
      Animals are adapted to handle cold winters and to breed and raise young quickly in the very short and cool summers.
      The soil is often frozen. Permafrost, or permanent ice, usually exists within a meter of the surface.
      Precipitation and Climate 
       The average annual temperature is only
      10 to 20F (-12C to -6C)
      Water is unavailable during most of
      the year. 
      Annual precipitation is very low, usually
      less than 10 inches (25 centimeters).
    • Biome Characteristic: Taiga
      The largest biome in the world.
      Winters are cold. Summers are warm. Lots of conifers grow here.
      Prone to wildfires. Many trees have adapted to this by growing thick bark
      Precipitation and Climate 
       The average temperature is below freezing for six months of the year.
      Total yearly precipitation in the taiga is 12 - 33 inches (30 - 85 centimeters).
      Although the cold winters have some snowfall, most of the precipitation comes during the warm, humid summer months.  
    • Biome Characteristic: Desert
      land of extremes: extreme heat and extreme dryness but sudden flash floods and cold nights.
      have so few trees and other vegetation
      Precipitation and Climate 
       Deserts are usually very, very dry.
      Even the wettest deserts get less than ten inches of precipitation a year
      there may be only a few periods of rains per year with a lot of time between rains
    • Biome Characteristic: Temperate Deciduous
      Has four seasons of winter, spring, summer, and fall.
      Animals and plants have special adaptations to cope with yearly/seasonal changes.
      The word "deciduous" means exactly what the leaves on these trees do: change color in autumn, fall off in the winter, and grow back again in the spring.
      Precipitation and Climate 
      Gets the second-most amount of rainfall per year
      Average temperature of the forest is about 50 degrees Fahrenheit.
    • Biome Characteristic: Grasslands
      Big open spaces
      There are not many bushes in the grassland. Trees are found only by rivers and streams. The grassland seems like an endless ocean of grass
      Grassland soil tends to be deep and fertile.
      Found on every continent except Antarctica
      Precipitation and Climate 
       Grasslands receive about 10 to 30 inches of rain per year
      If they received more rain, the grasslands would become a forest. If they received less, they would become a desert.
    • Biome Characteristic: Marine
      Marine regions cover about three-fourths of the Earth's surface and include oceans, coral reefs, and estuaries.
      Marine algae supply much of the world's oxygen supply and take in a huge amount of atmospheric carbon dioxide.
      The evaporation of the seawater provides rainwater for the land.
    • Biome Characteristic: Freshwater
      Freshwater is defined as having a low salt concentration — usually less than 1%.
      Plants and animals in freshwater regions are adjusted to the low salt content and would not be able to survive in areas of high salt concentration
      You'll find a wide variety of animal life in or around fresh water ecosystems...aquatic birds... amphibians..mammals and of course, a wide variety of fish.  And the water cycle is very important to fresh water ecosystems

      Terrestrial
      My Terrestrial Biome is Rainforest

      My Aquatic Biome is Marine Coral reef

    • My Biomes
      Terrestrial
      My Terrestrial Biome is Tropical Rainforest. A Tropical Biome has wet and dry climate. It is rich in biodiversity
      The rainforests are home to more worldwide species than all other biomes added together. About 80 percent of the world's known biodiversity could be found in forests.
      Aquatic
      My Aquatic Biome is Marine Coral reef. Marine ecosystems are very important for the overall health of both marine and terrestrial environments.
      In addition, other marine ecosystems such as coral reefs, provide food and shelter to the highest levels of marine diversity in the world.
    • My Biomes
      Aquatic
      Coral reefs are underwater structures made from calcium carbonate secreted by corals. Corals are colonies of tiny living animals found in marine waters that contain few nutrients.
      Most coral reefs are built from stony corals, which in turn consist of polyps that cluster in groups. But unlike sea anemones, coral polyps secrete hard carbonate exoskeletons which support and protect their bodies. Reefs grow best in warm, shallow, clear, sunny and agitated waters.
      Terrestrial
      The leafy tops of tall trees - extending from 50 to 85 metres above the forest floor - forms an understory. Organic matter that falls to the forest floor quickly decomposes, and the nutrients.
      Rainforests are partly characterized by high rainfall. This often results in poor soils due to leaching of soluble nutrients.
