The rainforest has more species of
plants and animals then any other
biome.
Rainforests cover 6 percent of the Earth's surface this number is going
down though because of deforestation.
The Rainforests get around 2,000 mm
of rain per year and the temperatures
range from 27-32.
You can find TRF (Tropical Rainforests)
between the tropics of Cancer and
Capricon.
As the Rainforest is warm and wet all
round year this makes it a good place
for growth.
Layers of the Rainforest
Bottom Layer (Forest Floor): Very little reaches the forest floor so the plants
grow very slowly. But when a tree collapses it lets in the light so all the plants
fight for the light so that they can grow. Hear are the animals which live
here:Jaguars, leopards, tigers, elephants, gorillas and lots of insects.
Understory: this layer stills gets a little a bit of light so the
plants have adapted to have not much light to grow and
photosynthesise these. Animals live here:Birds, butterflies,
frogs, snakes and lots of insects live here.
Canopy this is the second highest layer their height is around 30-45
metres high. The canopy layer blocks out light and catches rainwater for
the bottom layer and the understory layer. The Animals which live here
are: Birds, monkeys, frogs, sloths, lizards, snakes and many insects live
here some of these animals never go to the forest floor.
Emergents layer this is the top layer the height of this layer ranges from
around 40 metres and above. This layer though only has a couple of
trees this high. They have small, waxy leaves to prevent themselves from
drying out. The animals which live here are:Eagles, butterflies, small
monkeys and bats all live here.
Deforestation
What are the causes of Deforestation?
The causes of deforestation are that people want money,
land, farms, buildings,roads, room for cattle ranching,
ingrediants from the tree which are high priced for
example furnitures and homes and harvesting timber for
paper .
What are the impacts of Deforestation?
The impacts to Deforestation is that you are
emiting of more CO2 because their isn't enough
trees to take in the CO2.
Also when you cut down the trees you are also
killing animals and their habitats because some of
them live in the trees so when the trees fall you are
killing them because they might get squashed.
If we keep cutting down trees then in the future
people might start to die from not having enough
oxygen because we have cut down to many trees
down and their is to much CO2.
Sustainable developing
Selective Logging: Only the oldest trees are cut down, meaning most
trees are still left standing. This is less damaging as the overall forest
structure is kept which means the rainforest will be able to regenarate.
Replanting: New trees are planted to replace the
ones that are cut down this means there will be
trees for people to use in the future.
Education: Some local people are unaware of the
damage of deforestation can do. Educating these
people about the impact of deforestation and the
ways to reduce the impacts, decreasing their effect on
the environment.
Reducing demand for hardwood: there is a high demand for
hardwood eg mahogany from consumers in rich countries
which means that some tropical hardwoods are becoming
rare, some rich countries are trying to reduce the demand by
taxing imported hardwood or banning it.
Climate Graph ----->
A climate graph tells us what the climate is like in an area. The graph above
tells us that the yellow rectangles are the heat and the blue dotted lines are
how much rain water you get in this area every year.
