Transcript of Biomes
The average temperature is 4c to 18c.The wind is 0m/s to 6m/s.The sunlight is 30 to 55 degrees, the shortest day is December 21st.The average precipitation for grassland is between 25 to 57cm/y.
Tropical rainforest are covered in lush,green trees and plant life.They have many famous mountains and lakes an good example would be mount Kilimanjaro in Tanzania the tallest mountain in Africa. A good aspect of a rainforest is that mountains help shade parts of the forest away from the sun which is called albedo. Tropical rainforests are located along the equator,which means they receive a lot of sunlight which is known as Insulation. Abundance of water helps keep the sun from drying out the forest it also creates a humid climate.
The trees in the Taiga are mainly spruce, pine, and fir. The plants like icy and snowy winters.For example,the needles of the pine are very smooth to help keep water inside the dark casing. Some of the berry bushes that thrive in Taiga are blueberry, bilberry, and cow berry. Not that many common trees grow in the Taiga.Most of the animals in this Taiga are moose, snowshoe hares, arctic fox, arctic wolves, squirrels, ermines, elk, deer, wolverines, moles, lynxes, and grizzly bears.There are also birds,eagles, owls, peregrine falcons, and insects, such as mosquitoes, and ants.
Grasslands are areas filled with tall growing grasses.Different kinds of grass grow in different areas of the grasslands.Types of grasses that grow are buffalo grass, blue grama grass, needle grass, big blue stem, and switch grass and plants that grow are sunflowers, sagebrush,clover,asters,goldenrod, butterfly weed, and butter weed. A variety of animals live in the grasslands. wolves, turkeys, eagles, weasels, bobcats, foxes, and geese.A lot of smaller animals hide down in the grasses such as snakes, mice, and rabbits.
Rainforests are known to have many exotic plants and animals, which manly includes vines,and frogs.Lianas are part of the 90% vine species that grow in rainforests.They have thick, woody stems which are usually 3000 ft long.Lianas climb trees by attaching their sucker roots/tendrils to trees or they climb by winding themselves round the tree trunks.Lianas grow upwards toward the sunlight leaning on trees for help.
The tundra has very little trees and animals, because its very hard to survive in these harsh climates. The arctic willow or as its best known the rock willow could adjust very well to the harsh climates. Arctic willow is 15-20cm in height. It has very long branches that root when they touch the surfaces. Its leafs are oval shaped with pointed tips, wedge shaped bottom and have little stalks.When the arctic willow is at its strongest growth point it forms a pesticide to keep insects like the arctic wooly bear away.

Human population growth will cause the most damage to rainforests ( including other ecosystems) because humans search for new living stocks and food production not to mention using wood for fuel, construction and energy.
Tropical region's climate will change the least because nitrogen problems aren't as important. Growth in rainforests use more low phosphorus levels than they use nitrogen.
Deciduous Forests are found in parts of North and South America,Europe etc. The temperature of a Deciduous Forest is 14c to 27c.Also the wind mostly below's west.The precipitation is 75 to 150cm/y.Also the Deciduous Forest doesn't have any sunlight.
Desert climates are extremely odd. The average annual temperature is 12c to 27c which make the land very dry. The precipitation for a desert is less than 25cm per year, the Sahara desert for example has as little to 2cm per year. An extremely odd thing about desert is the sudden climate change it's really hot during the day and freezing during the night the deserts location is a huge part of the sudden change in climate.
Taiga is found around the earth,just south of the region of tundra.Taiga may be called boreal forest.Its temperature is 47c to 14c.The precipitation is 40 to 100cm/y much as snow.In summer the light is more direct.For example,in the warm months Taiga can have sunlight up to 24hrs per day.In winter the sun is tilted away and it mostly dark in the day.It has cool summers and cold winters.Also the wind is 0m/s to 10m/s.
Deciduous forests have a great variety of plant species. Most have three levels of plants and the other most are small so they are found on the forest floor.A plant that is found in the Deciduous Forest is a common lime tree it is a tall, stately tree.The common lime can live up to 500 years also the tree can grow to a height of 120-130 ft tall.Some of the animals that live in the forest are a white-tailed deer,least weasel,eastern chipmunk,american bald eagle etc.
The average annual temperature in the Tundra is -15c to 5c, it is mostly cold throughout the year. Summer comes for a very short period of time basically on 6 to 10 weeks.The wind blows constantly causing it to be cold,precipitation in the tundra is 6 to 10 inches a year which is mostly melted snow.
Tundra is also called the 'land of the midnight sun', even the sun cant warm up the tundra that much.The tundra has low insulation and a high albedo. It gets a very low amount of solar energy and lower layer's of then ground are permanently frozen, thus it having low insulation and a high albedo. This affects the climate because it keeps it cold.
Deserts are very dry and rarely get any moisture thus the reason for having high levels of insulation, the heat from the ground makes the rain evaporate before it can come down as rain depending on how much it is. Another reason for having a high level of insulation is that the sun rays beat down directly overhead not a lot of atmosphere to protect it from the radiant energy. Deserts do also lack water and plants thus the reason for not having a sufficient amount of heat capacity to retain thermal energy, that's why its cold at night.
Their aren't a very large amount of plant and animals that reside in Deserts the cause being its extremely hot climate. Cactus's and Armadillo lizards are mainly seen in Deserts.Armadillo lizards nostrils are formed into tubes that help hunt for food or predators. It is normally slow but it can run for cover pretty fast when it senses danger.The head, body and club-like tails are flat so it can easily wiggle into rocks crevice for shelter. It rolls itself into a armadillo when it feels threatened thus its name
Human activities are mainly responsible for desertification (process of productive crop-land turning into non-productive desert like environments). The activities are deforestation it removes plants that anchor the soil and people overuse natural resources killing of many plants that should be absorbing water and fertilizers.
The most sever threat to the tundra is global warming. Scientists believe the effects caused by global warming could eliminate the arctic regions, including the tundra forever.The frost that melts because of global warming could change the landscape and the kinds of animals that live their. A lot of things are changing because of global warming, their is proof of this as well. The arctic regions are losing a lot of things part of the landscape like frost. who knows what could happen if this continues.
Animals and plants in deciduous forests have special adaptations to cope with seasonal climate changes, especially winter.Migration and hibernation are two adaptations used by the animals in the Deciduous Forest.For example,the White Birch.The White Birch Planet have leaves, sap and lumber.The White Birch is also a small to medium sized tree which grows to 70 or 80 feet in height.The white birch is found in Newfoundland, Labrador, Canada, and from United States etc. It likes colder climates.
Grassland are large, rolling terrains of grasses, flowers and herbs.One of the famous animals that is found in the grassland are a African Elephant .There 24 1/2 ft tall.It has larger ears and tusks than the Asian species and two finger-like extensions at the end of its trunk.Also they love eating leaves.
Also the trees in Taiga are mainly spruce, pine, and fir. The plants adapt to harsh weather in this environment, like icy and snowy winters. For example, the needles of the pine are very smooth to help keep water inside the dark casing. The spruce's cone like shape allows them to shed ice and sleet more efficiently.

The most sever threat to the Grassland is global warming because continued global warming could turn current marginal grasslands into deserts as rainfall patterns change.Also these days Grassland soil is rich, and almost anything can be grown there. But poor agricultural practices can ruin soil and turn grassland into lifeless, barren spaces.
It is no coincidence that a good deal of the human population is found in areas that once supported temperate forests.One of the problems with the tropics is the prevalence of parasitic diseases found there, many transmitted by mosquitoes or other insects - and this is less of a problem in temperate areas.
The impact of humans on Taiga is acid rain because it is causing significant problems for the Taiga forests.Acid rain is rain that is more acidic than normal. Also scientists have discovered that air pollution from the burning of fossil fuels is the major cause of acid rain.
