3. Desert Biome This biome is the driest; it only receives 50cm of rainfall a year about 10% of the rainfall in the rainforest. Its plants and animals have to survive in an environment with little water and dramatic temperature changes from day to night. Some animals and plants may find if difficult to adapt, but reptiles and cacti thrive in these conditions.

4. Forest Biome Forest biomes cover about 1/3 of the Earth’s land surface. They are dominated by trees and contain many different plants and animals. Forests take in the carbon that we exhale and give off the oxygen we breathe in, making them really important to our survival.

5. Fresh Water Freshwater is water that has a salt level of less than 1%. Most species living in freshwater cannot live in salt water, although there are some exceptions. This biome also plays an important role for life on Earth. It provides drinking water for humans and other animals, it is also vital for plant growth.

6. Grassland Biome It may not surprise you to hear that grasslands are filled with grasses. However, the length of the grass and the number of trees within these biomes vary depending on the amount of rainfall. Since rainfall in the grasslands is lower than rainforest but higher than desert, trees exist, but they are limited to growing near streams and other water sources.

7. Tundra Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturia, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation. Tundra is separated into two types: arctic tundra and alpine tundra

8. Marine This biome covers more of the Earth’s surface than any other – about 70%. Some areas are so deep that they can contain entire mountains and even volcanoes. Like many of the other biomes on the planet, they play an important role. This biome provides most of the rainwater that comes down from the sky and it is home to some of the planet’s most diverse species Click on The dolphin for multiple choice questions!

9. Multiple choice question! Which Biome is the driest and has less than 50 cm of rainfall a year? A.Grassland BiomeGrassland Biome B.Marine BiomeMarine Biome C.Desert BiomeDesert Biome

10. A. Grassland Biome oops! Try again A Grassland Biome is filled with grasses, has rainfall activity and has very tall trees Click on the fish to go back

11. B. Marine Biome oops! Try again A marine Biome covers about 70% of the earths surface This biome provides most of the rainwater that comes down from the sky and it is home to some of the planet’s most diverse species Click on the fish to go back

12. C. Desert Biome WOOOHOOO!! That is correct a Desert Biome is the driest biome with little to no rainfall a year
