Transcript of Introduction
Hello there! Welcome to Khans Summit Adventure, Its time to climb the summit of the 8 biomes, here you will learn just what you need to know about biomes, enjoy!
Well you have reached the end of the summit, congratulations, i hope you learned something new today about biomes, theres a lot to learn still about these amazing places!
Second stop : Boreal Forest
- Located in the northern hemisphere, most are found in Canada and Russia. 45* and 65* latitude across Canada and 55* and 65* Latitude in Russia, Finland and Scandinavia.
- Precipitation is 30 cm to 85 cm annually, the tempature often drops to -40*C
- Short summer, the growing season has an average of 50 days, rough terrain and very wet soil.
- Only a few plants survive in this climate so it has a low diversity.
- The trees are mainly coniferous, such as black and white spruce, and little light reaches the floor.
- Shrubs, Mosses, Lichens, Shrub species like willow, alder and mountain ash, other plants have also adapted to the biome like herbs.
- Warblers migrate south in the fall, small mammals like chipmunks and shrews make a hole in the winter to stay warm
- Caribou's, Grizzly bears, moose's, wolves and other small species also stay in the Boreal forest,
there is a variety of species.
- The Boreal forest represents 29% of the worlds forest cover
- Boreal is named after a Greek god.
- Boreal is also referred to as taiga.
Third Stop : Temperate Deciduous Forest
- Found in eastern half of the United States, Canada, Europe, parts of Russia, China, and Japan, Occurs above 23.5* north latitude and between 23.5* and 38* south latitude.
- The average temp of the forest is about 50 degrees F The average rainfall is about 75 cm - 180 cm, with equal amounts of precipitation through the year. -30*C in the winter time and 30*C in the summer.
- This forest has 4 seasons, Winter, Spring, Summer and Fall, With very hot, Summers and very cold Winters, the animals and plants have special adaptations to get used to this it also has a long growing season.
- The plants grow in 4 to 5 layers, They have a lot of plant variety, Lichen, Moss and Ferns are found here, other small plants can be found on the floor.
- Tall Maple, Oak and Birch trees are in the conopy layer, shorter trees in the second layer, Shrubs in the third layer, berries take the fourth layer, and ferns, herbs and mosses on the final forest floor.
- Since the forest has many layers it benefits for the animal habitats, Squirrels, Rabbits, Skunks, Cougars, Deer and more gain help from this.
- Some Mammals hibernate and many birds migrate to warmer areas during the Winter time.
- The Biome has 4 seasons, Winter, Spring, Summer and Fall.
- Temperate deciduous forests receive 30 - 60 inches of rain fall each year
- The animals in this biome have to be really good at adapting to deal with
the changing seasons.
First stop :Tundra
- Located in the upper northern hemisphere, 60* to 70*
Spread into 2 types of arctic and alpine Tundra
- 20% of the earth is covered with Tundra
- One of the coldest places in the world
- Always has a layer of permanently frozen soil. (permafrost)
- Precipitation is less than 25 cm, in the summer the average is 3*C to 12*C, Winter avg from -20*C to -30*C
-Many Tundra animals grow slowly and reproduce less than usual.
- Animals in the Tundra are Caribou, Armine, Arctic Foxes, Bears and more.
-No trees grow here since the season is short, and many plants grow near the ground where they get heat.
- Plants that grow in the Tundra are Moss, Small grasses, Lichens, Bearberry and more.
- The Tundra is very cold and summer is short
Fourth Stop : Temperate Rainforest
- The rainforest runs from from 38* to 56* south latitude along South America and 38* to 61* north latitude along the coast of North America, including coast of B.C, New Zealand and part of southern Asia also have Temperate Rainforests.
- Rainfall goes beyond 200 cm a year, avg tempatures are from 5*C to 25*C.
- The forest occurs in narrow strips along the coastlines.
- The trees and plants in this biome grow very very tall because of high precipitation.
- Plants like Moss grow on trees and branches which gives the biome a jungle like look.
- Coastal redwood, Mosses, Lichens, ferns, fungi, and other plants grow in this biome.
- Most of the animals live near the forest floor, because they will be protected from the wind, rain and other disasters.
- Birds and small mammals eat the seeds that fall on the floor.
- Animals in the Forest have a variety, Birds that eat the insects in the tree bark, hawks, snowy owls, woodpeckers are also found in this biome. Mammals include Deers, Raccoons, Red foxes and more.
- Temperate rainforests are divided into three layers, the canopy, understory, and last the forest floor.
Fifth Stop : Grassland
- The grassland that is found in Canada is referred to as temperate grassland or the prairies, it is found above 23.5* north latitude and below 23.5* south latitude, found from 5* to 20* from the north and the south of the equator in Africa, South America and also Northern Australia.
- Precipitation is 25 cm to 100 cm, hot summers of 30*C and cold winters below -10*C. In tropical grasslands precipitation is 50 to 130 cm and the daily tempature is 20*C to 30*C.
- Flat land, very rich soil and fertile because of deep roots, tropical grassland isn't as rich because the nutrients are removed by heavy rain, grass fires are also common.
- Trees are scarce since their is limited rainfall, there is deep roots, narrow leaves but colorful leaves, grass like blue grama and buffalo grass are adapted well for droughts since they have very deep roots.
- There are not many plants in the grassland, many are grasses like buffalo grass, if there is 30 inches of rain a year in an area the plant will grow alot.
- Some trees, like aracia have thorns so animals can't eat them.
- Big animals are present in big numbers since there is alot of grass.
- There is a low diversity of animals in the grasslands but a high abundance, Antelopes, Giraffes, Zebras, Lions and many more animals are found in the grasslands even Mice and Rabbits are in grasslands.
Sixth Stop : Tropical Rainforest
- Located 4800 wide from around the equator, 23.5* north latitude and 23.5* south latitude.
- The forest covers alot of northern and southern America, central America, Central Africa and southeast Asia.
- Rainfall is about 250 cm er year, tempature is 20*C to 25*C throught the year.
- Poor soil and the nutrients are recycled, the soil is poor because the rain washes away the minerals and the floor is dark which maxes the growth of plants and they can only grow so much.
- The Tropical Rainforest has the largest number of plant types, they have a variety of plants in this biome.
- Tall trees take alot of sunlight, and alot of the plants grow in many layers.
- Epiphytes, Bromeliads, Orchids and many other plants grow in this biome.
- Orchids and other small plants grow on trees so they can reach sunlight since the sunshine shines on trees.
- Tropical Rainforests have the most diversity of animals, and most of the animals adapt to live in the trees since the forest floor has little amount of vegetation.
- monkeys, birds, snakes, frogs and other animals are common in the biome, many of the animals hide in the trees instead of going down on the floor, the trees provide them with shelter, give them food and is good for hiding from their predators who might not be able to reach them.
- Many animals compete for food so not everyone gets what they want, so some animals adapt to a certain type of food that others don't like so they can acquire the food easily.
- About 1/4 of natural medicines have been discovered in rainforests.
- Alot of water comes from tropical rainforests, so it is a critical thing needed in the world.
Seventh Stop : Desert
- Hot deserts are found around every continent with latitudes of 30* north and south, but cold deserts are found in dry regions that are above 30* north latitude and below 30* south latitude.
- Hot deserts are in the Sahara, Arabian Desert and more. Cold deserts are found in places like the Antarctic and Greenland. Some places have both Hot and Cold deserts like the Nabid desert.
- In hot deserts the rainfall the rainfall is less than 25 cm, hot days will average up to 38*C and cold nights averaging up to 7*C. Cold Deserts also have rainfall less than 25 cm, summer days average from 21*C to 26*C and winter days from -2*C to 4*C.
- Hot deserts rainfall is unconsistent sometimes there is little rainfall and sometimes there is alot but in a short period of time, cold deserts have precipitation falling as snow, but it does rain in the spring time.
- There is not much of a variety in the deserts for plants, in a hot desert the types of plants are Cacti, Saguaro, Palm trees and more.
- Cold deserts also have few amount of species, most of the plants are less than 1 m tall the types of plants are desert shrubs that are deciduous but some are just partially deciduous, sagebrushes, and some others.
- In hot deserts reptiles are the most common type of animals there, toads and scorpions bury themselves inside the ground to get through the times of heat and drought they can't withstand.
- Animals in cold deserts consist of foxes, lizards, pocket mice, etc.
- Animals in hot deserts like to come out during the night when its much cooler and not as hot.
- since there isn't much water in the desert biome, animals will store water in their bodies.
Final stop : Permanent ice
- Permanent ice is found in the Arctic, Greenland and Antarctica.
- Precipitation is less than 50 cm, most is from snow falling, the tempature has been as low as -89*C in Antarctica the average is -30*C, summer tempatures range from 9*C from the coast and -30*C inland and the average Arctic summer rates is from 3*C to 14*C.
- Very strong winded biome and little soil, there is not much fresh water because the water would be very cold and not good to drink since it is cold all year long.
- There is around 100 species of moss in Antarctica but only 3 types of flowering plants.
- Many types of moss species grow in the Arctic but few species grow in Antarctica.
- Animals must have alot of fat and skin to stay warm in this biome since it is extremely cold and you wouldn't be able to survive without good material.
- Polar bears, Seals, Foxes, Penguins, and some insects live in this biome.
- Bears have very thick coats which keep them warm, but animals like walruses don't have as much so they lay together in herds with alot of walruses to keep warmth.
