The tropical rainforest biome is characterized by warm temperatures year-round, high precipitation levels, and abundant plant and animal diversity. Temperatures in the rainforest average around 77°F and precipitation levels receive between 200-600 cm of rain per year. The dense canopy supports a wide variety of plant and animal life adapted to the humid conditions, including parrots, monkeys, frogs and fig trees.

temperatures in Iquitos, Peru.
•Write two facts about precipitation.

3. The X-axis has the

ways that Barrow
,Alaska and Iquitos
Peru differ in
precipitation
amounts.

4. Rainforest Facts
• Warm temperatures, wet weather, and
abundant plant growth
• Warm because they are located near
the equator

5. Why Diversity???
• Since temperatures are constantly warm in
the rainforest, animals can spend their time
reproducing.. They can reproduce more often
• This explains how animals and plants have
gotten to be so diverse.

6. Characteristics
• Average temperature is 77˚F
– ranges from 68-93 F
• Receives 200-600 cm of precipitation
per year!

7. The rainforest has…
• Has the greatest variety of organisms
on Earth!

8. 4 Zones of Rain Forest
1. Forest floor (bottom)
– Many insects, reptiles, amphibians
2. Understory
– Dark, cool
– Under canopy leaves but above ground with shade
tolerant shorter plants
3. Canopy
– Upper parts of some trees
– Full of life; insects, birds, reptiles, and mammals
4. Emergents (top)
– Giant trees much higher than average canopy tree
– Birds and insects are found here

13. Adaptations
• Because there are so many different types of
animals, there is a large amount of
competition for resources.
• For this reason animals become specialized,
which means they eat what few others eat

14. • Parrots and toucans developed big
strong beaks to crack nuts

15. Animal Adaptations
• Some are poisonous and use bright
colors to warn predators (poison arrow
frogs)
Dart Frog Brazilian Wandering Spider – one of the
most poisonous spiders in the world

16. Animal Adaptations
• Many use camouflage to blend into the
forest to avoid predators

19. The Aye-Aye

20. Primates Adaptations
• Primates have long arms to swing around in the trees.
• Opposable thumbs to eat food with and hang from trees

21. More Adaptations
• Philippine Eagle
has a hooked
shaped beak to
tear flesh with.

22. Plants
• Bengal Bamboo
• Durian
• Jambu
• Rafflesia
• Kapok Tree
• Mangrove Forests
• Strangler Figs
• Tualang
• Passionflower
• Liana
• Orchid
• Bougainvillea
• Curare
• Coconut Tree

24. Plant Adaptations
• There are more than 1400 varieties of
plants in the rainforest that can be used in
cancer treatment
• Leaves of trees have drip tips or grooves
to allow them to shed water quickly so
weight of water does not break branches
• Dark understory leaves are very large to
trap what little sunlight they can get
• Some leaf stalks turn toward the
movement of the sun
