Terrestrial Biomes

What is a Biome?A biome is a large geographical area of distinctive plant and animal groups adapted to that particular environment. The climate and geography of a region determines what type of biome can exist in that region.Major biomes include deserts, forests, grasslands, tundra, and several types of aquatic environments.

Tundra : terrestrial biome

Scientists call TUNDRA the frozen cold ecosystems found near the North part of the Earth.

Winters are LONG AND COLD. Summers are SHORT AND COOL.

Animals and plants in the tundra biome:Animals: seals, polar bears, arctic hares, and arctic foxes survive in the long cold winters.

Deserts: terrestrial biome.

 There are both hot and cold deserts. Antarctica is the largest desert in the world, while the Sahara in Africa is the largest of the hot deserts.

Hot and dry deserts- Most Hot and Dry Deserts don't have

many plants. - They have some plants. - The animals in deserts can survive

under ground.- animals can’t live in the hot sun and

heat. They only come out in the night when it is a little cooler.

Animals live under ground

To keep cool and fresh

Cold and dry deserts- A cold desert is a desert that has snow

in the winter.- Plants don’t grow because is not warm.- The animals in Cold Deserts also have to

live under ground, in this case to keep warm, not cool

Grasslands: terrestrial biome

- Grasslands have few trees, and extensive grasses, and many different small and large animals.

- Some of the largest land animals on Earth live in grasslands, including American bison, elephants, giraffes, etc.

Rainforest: terrestrial biome

- The tropical rain forest is a forest of tall trees in a warm region.

- Rain forests belong to the tropical wet climate group.

- Rainforests now cover the 6% of Earth's land surface.

- Scientists think that more than half of all the world's plant and animal species live in tropical rain forests.

- Tropical rainforests produce 40% of Earth's oxygen.
