Hello, friends. Today we'll learn about the biomes. 00:00:00
A biome is a huge region of Earth that has a certain climate and certain types of organisms. 00:00:07
Four major biomes are tundra, forest, grassland, and desert. 00:00:13
Let's learn about each one by one. 00:00:19
At first, the tundra biome. 00:00:22
Around 20% of the Earth's land surface is covered with this biome. 00:00:25
The tundra biome is the coldest among all the biomes. 00:00:29
The average temperature in the tundra is approximately minus 18 degrees Fahrenheit. 00:00:35
Some lichens and small shrubs flourish in the Arctic tundra. 00:00:41
Careful, polar bears live in the tundra. 00:00:46
They are the largest carnivorous land mammals on Earth. 00:00:50
Hmm, due to harsh climate, people do not prefer to live here. 00:00:54
Now we're going towards the forests. There are three types of forest biomes, 00:00:59
the rainforest, the temperate forest, and the taiga. More than half of the world's species 00:01:06
of animals and plants are found in the rainforests. Ah, look at that cute monkey. 00:01:13
Jaguars and monkeys, etc. can be seen here. Climate is typically warm and wet. Temperate 00:01:19
Red forests have four distinct seasons, winter, spring, summer, and fall. 00:01:27
You'll find various deciduous trees in this biome that lose their leaves in winter and 00:01:33
bud new leaves in spring. 00:01:39
Raccoons and red foxes are very common in this biome. 00:01:41
The taiga is a forest of the cold and sub-Arctic region. 00:01:45
Long, severe winters last about six months, with average temperatures below freezing. 00:01:50
Mammals living in the taiga include bears and squirrels, etc. 00:01:57
Let's move towards the grasslands. 00:02:02
Grassland biomes are places that receive more rain than deserts, but less precipitation than forests. 00:02:06
Most of the plants here are grasses and wildflowers, which don't need much water. 00:02:14
In Africa, grasslands are called savannas, and in South America, they're known as pampas. 00:02:19
The largest grasslands are in East Africa. Grasslands support a variety of species. For 00:02:26
example, zebras and giraffes live in the savannas. You'll see foxes, skunks, etc. in the pompous 00:02:33
grassland. Now we're going to see the deserts. Deserts. Deserts are the driest places on the 00:02:41
earth. The low survival of the desert biome creates soil that is very dry and difficult 00:02:50
for people to survive and plants to grow. Some deserts like Sahara Desert in Africa is hot, 00:02:56
while others like the Gobi Desert in Asia is quite cold. In hot deserts, you'll often find 00:03:04
cacti and sagebrush. Camel is the most common animal you'll see in a hot desert, as it can store 00:03:11
lots of water. It's very important to preserve all types of biomes as each houses various unique 00:03:18
forms of life. Show the biome types to your friends. Very good. Now you know a lot about 00:03:25
biomes. Stay tuned for more videos. Bye-bye. 00:03:35
