Transcript of Science 10 Unit D2.4

Earth's
Biomes Relationship
between Biomes
& Climate Thank you for your attention! Each Biome has different annual
temperatue and percipitation
levels. Climate plays a major role
to determind the plants
and animals that can
grow in that biome. An open system interacts with its surroundings. A Biome
exchanges energy and matter with its surroudings so
there for it is an open system.

A closed system only exchanges matter with its surroudings.
An example of this is the Earths hydrosphere
Tundra. Tiaga is located just north of the Tundra regions. Most
of the Tiaga Biome is made of evergreen conifer trees.
Examples would be fir, pine, and spruce. The Tiaga
is often also known as the boreal forest. It has higher percipitation levels and a higher everage temperature.
Due to the latitude of the Tiaga it has lover growing
seasons as a result more plants can survive.
The leaves of trees contain resin witch makes them
resist freezing and drought conditions.







Biomes Are Open Systems
Earths Biomes Tiaga Is found in the Artic regions of both North America and Eurasia.
Most Tunrdas are found at the latitude 66.3 this latitude means
the amount of daylight in each day varies all through out the year.
Since in winter there is very little sunlight the Tundra Biome recieves
very minimal solar energy. The yearly amount of insolation is the
loweest amount throughout all the Biomes. Plants in the Tundra
have a very short life so they have to reproduce in the short
summer season. The deciduous forest is located in parts of North and south
America, Europe, Asia, Japan and alost Australia.
Oaks, maples, and Ash are the most common trees in the
Deciduous forest. They all lost their leaves and thats what
makes them the most known trees. The insolation throughout
the year varies so it has a longer growing season. The winter
and Summer months are easily distinguished. The Maple tree
is very capable of photosynthesis but the leaves easily freeze,
and lost very large amounts of water through transpiration.
Because of the water lose the trees do not need much water
during the winter.







Deciduous Forest The grassland biomes mostly consists of grass and had very
few trees. It has very few trees because it only gets at least 20
cm of water per year and that isn't enough water to suport the
growth of trees. The average temperature is roughtly 4 - 30
degrees celcius. In North America the grasslands are mostly
called prairies but can be called different names. Grasslands
in Afria are called Savannas.








Grassland Rain forests have a large diversity of plants and animals.
They have more than 200 cm of water per year and are always
warm so they can grow plants all year round.The high amounts
of plant growth in the Rain forest supports a large amount of
animals. The rain forest has many different types of trees
due to the variation of sunlight in different areas.









Rain Forest The desert biome alwats has less than 25 cm of rain yearly.
Because the low amount of rain annually it has very little plant
life. The high levels of insolation makes it very hot during the
day.
Since there isn't much water or plants the desert cannot retain
thermal energy so it gets very cold during the nights.
The Cacti are the most known plants in the desert because
they are able to store water so they can tolerate drought.
Animals and plants in the desert need very little water to
survive and are only active at night because of the colder
weather.
