Location of Tropical
Rainforest
Tropical Rainforest biomes are found in
the lower latitudes, around the equator.
Some places you will find Tropical
Rainforest are in Australia, the
Southeast of Asia, the Southern portion
of India, South America, and many
other places! You may not be aware,
that a Tropical Rainforest can be found
in many different types of terrain. This
includes mountain, plain, and river
valleys. Rainforest only cover 6% of the
Earth’s surface.
Tropical rain forests are found only in a relatively small area on
Earth. Between the latitudes of about 25 degrees North and
South of the equator. Originally, the rainforest covered much
vaster areas of the world but over time, when humans started to
build new areas to use for our own needs much was used or
taken. After “man’s activities,” only 2% of the Earth’s surface is
covered by Tropical Rainforest. These Rainforest are found in 85
countries in the world but the largest rainforest is found in the
Amazon river basin in South America, much of which lies in
Brazil. The second largest rainforest is found in the Congo Basin
in Africa. There are five major tropical rain forest regions in the
world: Central America, the Amazon Basin, Africa, Southern Asia
and Australia.

Sunlight
• Sunlight is need for
photosynthesis which is an
important abiotic factor for most
living things in a tropical rain
forest. Sunlight creates
producers which is important
because sunlight provide
food for first and secondary
producers.
Water
• Water is an important
because all organisms
need it. All living things
need water to carry out
their life processes. Water
is also needed
for the photosynthesis
of plants. Most organisms
depend on algae and
plants for food.
Oxygen
• Oxygen is need for
most living organisms
in a tropical
rainforest. It is so
important that your
body can go only a
few minutes without
it. Organisms that live
on the land obtain
oxygen from the air,
which is twenty
percent oxygen.
Soil
• Soil in the tropical rainforests
is very nutrient poor. The
topsoil is only one to two
inches deep. The only reason
plant life is so abundant is
because the plants store the
nutrients in themselves rather
than getting them from the
soil. When plants decay,
other growing plants tap the
nutrients from the dead matter
and reuse nutrients left over
from that plant.
Climate
•
A tropical rain forest’s climate is
warm, wet, and humid. Tropical
rainforest’s climate have no
pronounced summer or winter. The
average daily temperatures are at
around 26.8 degrees Celsius.(80.3
degrees Fahrenheit) Extensive cloud
cover and heavy rain prevent
temperatures from rising to 33
degrees Celsius.( 91.4 degrees
Fahrenheit) In a tropical rainforest
there is never frost. Rainfall varies
widely from a low of about 250 cm
of rain per year to about 450 cm of
rain per year. That means a range
from about eight to fourteen feet of
rain per year.
Biotic factors
• Biotic factors are the
living things that make
up an ecosystem.
• There are many Biotic
factors that make up
the tropical rainforest.
Such as plants, and
animals.
ATTRACTIVE COLORS!
• Plants bright colors tell
some animals, “I’m
poisonous!”. Even if
they’re not, bright
colors trick animals or
other insects willing to
eat it.
VENUS FLYTRAPS!
• Venus Flytrap is a plant
that eats insects for
food. Its bright colors,
and sweet nectar
attracts the bugs.
Then…SNAP! The bug
becomes dinner.
FOOD!
• These plants are food
for certain herbivores in
the tropical rainforest.
Animals in the Tropical
Rainforests
There are so many
unique animals in the
tropical rainforests
because of the climate,
biotic factors, and
abiotic factors.
Silver Arawana
The Silver Arawana is known
as the “water monkey” because
it can jump out of floodwaters
and snatch beetles and spiders
from nearby tree branches. It
has a unique horizontally
divided eye structure, which
enables it to search two worldsabove and below water-for
prey.
Kinkajou
The Kinkajou is a nocturnal
animal, which means it
only comes out at night. It,
surprisingly, belongs to the
raccoon family even
though it looks and acts
like a monkey. Its tail is 18
inches long, while its body
is only 10 inches long. The
Kinkajou uses this long tail
as an extra arm to swing
from tree to tree.
Purple Martin
The Purple Martin is a
songbird known for its
warbling songs. The males
make a unique clicking sound
at the end of their songs. They
are fast and strong in flight.
Actually, they are so good
that they can catch their food
and water in flight. The Purple
Martins are monogamous,
which means they only mate
with one other bird. They have
relationships like faithful
human relationships.
Goliath Bird-Eater Spider
The Goliath Bird-Eater Spider
spans 7 inches with its legs
and weighs nearly a quarter
pound. It eats big prey, but the
prey is never bigger than the
Goliath Bird-Eater Spider’s
size. When it rains, this spider
goes to the tree trunks where it
waits in ambush to grab onto
some food. It has a poisonous
bite and has irritating
abdominal hairs that can flick
at eyes and the skin of
attackers, causing humans to
itch and smaller animals to
have more serious reactions.
