  • Freshwater

  • 65 °F to 75 °F in the summer and

  • 35 °F to 45 °F in the winter.

  • Marine

  • The temperatures vary widely but average around 39 degrees Fahrenheit


  • The average yearly precipitation can add up to over 100 inches.(ocean)

  • Fresh water varies.


Loctus, Water Irises, Oxygenator and Seaweed


Sea Otter, Sea Urchin,Whale,Dolphin,Bass,Guppy

Food Chain


  • Whale-Sea otter-sea urchin
  • Bass-Guppy-smaller fish



    • The weather of the marine biome is very harsh, due to the ocean currents. These ocean currents create massive hurricanes and typhoons. Another role in the weather of the marine biome is the wind. The wind over the ocean creates large waves.

  • The climate of this Biome is greatly diverse depending on the region.

World places


  • Over 70% of earth
  • All continents

  • Fish eat fish and fish eat plants
Fun Facts
    • Freshwater biomes contain 3% of the earth’s water. 99% of that 3% of water is ice or it is located under the surface in aquifers.

    • Freshwater biomes consist of more than 700 different species of fish including trout, carp and catfish. They contain 41% of total fish species found in the world.

    • There is about one cup of salt for every gallon of water in the ocean.

2 Kinds: Savanna and Temperate

  • Temperate Grasslands have hot summers and cold winters
  • Savannas are warm year round

There are rainy seasons and dry seasons.

  • 25% of Earth is covered by grasslands
  • Soil in the grasslands is extremely fertile.
  • Much of the grasslands are used for farming
  • Fires are important to make sure invasive plants don't take over

¼ of all medicines we use comes from rainforests. More than 1,400 varieties of tropical plants are thought to be potential cures for cancer. Rainforests cover less than 6% of Earth’s land surface. Rainforests produce 40% of Earth’s oxygen.

The word "Deciduous" means "falling off or out at a certain season". That explains why deciduous forest means a forest in which the leaves fall off the trees when the winter comes.

The deciduous forests are located in the temperate zone above the tropical forests and below the coniferous forests. Most of Europe, the eastern half of North America, parts of Japan and Asia were once covered with large deciduous forests. Most of the deciduous forests have now disappeared but many of the trees still grow in deciduous forest biome.
