Geography TRF ecosystems
- Tropical rainforest layers
- location of TRF
- Located between tropic of cancer and tropic of Capricorn and along the Equator
- examples
- southeast Asia,Central America,South America,western Africa

- Located between tropic of cancer and tropic of Capricorn and along the Equator
- forest floor
- Very little light reaches the forest floor (2%) - so plants grow slowly.
- The ground is covered in fallen leaves, rotting branches and twigs and a network of shallow roots.
- When a tree falls, light is able to get in. This encourages young plants to grow fast. They compete for the extra
light and soon fill the gap.
- Jaguars, leopards, tigers, elephants and gorillas and lots of
insects live here.
- Very little light reaches the forest floor (2%) - so plants grow slowly.
- under canopy
- Low light conditions (2-15%).
- Quite open - there is only dense vegetation along rivers and in openings where light gets in.
- Plants adapted to low light grow here.
- Birds, butterflies, frogs, snakes and lots of insects live here.
- Low light conditions (2-15%).
- canopy
- The second highest layer - 30-45 meters.
- The crowns of the trees knit together to form a dense canopy.
- The canopy blocks out the sun from lower layers and intercepts (catches) rainfall.
- It contains the most plant species.
- Birds, monkeys, frogs, sloths, lizards, snakes and many insects live here. This layer contains the most
animal species. Some creatures never go to the forest floor.
- The second highest layer - 30-45 meters.
- emergent layer
- The tallest layer - over 40 metres.
- Contains only a few tall trees which grow taller than the trees of the canopy.
- The plants are made for living in dry conditions because it’s very sunny.
- They have small, waxy leaves to prevent them drying out.
- Eagles, butterflies, small monkeys and bats all live here.
- The tallest layer - over 40 metres.
- layers of the rainforest
- location of TRF
- Climate graph
- line graph on top = temperature
- bar graph on bottom = percipitation
- months along bottom
- rainfall (mm) right side
- temperature (c) left side
- why we need the TRF
- river networks
- oxygen - the Rainforest vegetation takes in carbon dioxide and gives out oxygen
- medicines - a quarter of all natural medicines were discovered here
- undiscovered species
- food, eg vanilla, chocolate, nuts, ginger
and pepper
- resources, such as rubber and bamboo
- wood
- minerals
- river networks
- adaptations
- the process of change by which an organism or species becomes better suited to its environment.
- examples
- camoflauge
- nocturnal
- tails for balancing
- long finger or claws to help grab on to branches
- beaks to get fruits and catch prey
- camoflauge
- the process of change by which an organism or species becomes better suited to its environment.
- sustainable development
- economic development that is conducted without depletion of natural resources.
- how to stop it
- buying from companies that do sustainable development
- buying from companies that do sustainable development
- planting a tree every time you cut one down
- selective logging
- Monitoring making sure it's legal
- selective logging
- legal logging
- making sure people understand consequences
- economic development that is conducted without depletion of natural resources.
