Tundras are Polar. The average temperature of a tundra is -70 degrees ferenheight. It snows about 6-10 inches a year. There aren't many plants, but the ones that are there are shrubs, sedges and moss. These plants can only grow to be about 3 inches deep, because the ground further than that is frozen. Shrews, wolves and foxes are the predators of tundras. Mosquitoes live in tundras during the summer. They can keep themselves from freezing by replacing their bodies with a chemical called glycerol.
Forests are Mid-Latitude. The average temperature ranges from -30 degrees celcius to 30 degrees celcius. They get a rainfall of 75-150 cm anually. Oak, Hickory, and Beech trees- among many others- grow tall to make habitats and shade for the animals. Squirrels, Rabbits, and Deer live in Forest biomes.
Grasslands are Equatorial. They get about 20-50 inches of rainfall per year. There is a wet and dry season. Trees, Grass, and Shrubs are the plants of grasslands, and they can store food in their roots and lice off of it in the dry season. Elephants, Giraffes, and Zebras are some of the many animals that live in Grasslands. Elephants can eat almost any part of a tree, even the bark.
Dry Biomes are Mid-Latitude. They receive less than 50 cm of precipitation each year. There are almost no plants in dry biomes, only specialized vegetation that can survive with barely any water. Reptiles and Kangaroo mice live in these biomes, and to live here they must be adapted to go long periods of time without water.
Freshwater Biomes are Mid-Latitude. The average temperature of the water surface can be 22 degrees celcius in the summer, and 0 degrees celcuis (frozen) in the winter. Freshwater Biomes are home to floating aquatic plants, including algae, that are adapted to live in the water. Fish, crustaceans, and amphibians live in freshwater as well, and are adapted to live in only fresh water. They would die if they were put in salt water.
Marine (Ocean) Biome
Marine (Ocean) Biomes are found all over the globe. Temperatures vary, but they are all warmer on top and very cold at the bottom where there is no sunlight. They are filled with fresh water and aquatic plants. Coral lives like a plant and an animal in these biomes. Starfish and Octopi are two other animals in Marine biomes, and opposite of fresh water, they can only survive in salt water and would die in a freshwater biome.
