Tropical Rainforest
Michaela Mohrey
Location
• North central
America, South
America, Africa, Asia,
Australasia
Abiotic factors
• A forest of tall trees.
• A region of year round warmth.
• Temperatures rarely gets higher then 93. degrees
or drops lower then 68 degrees.
• Humidity is between 77 and 88%.
• More then 100 in. of rainfall each year.
• Almost all rain forests are near the equator.
• Rainforests cover less then 6% of the earths land.
• Tropical rain forests produce 40% of the earths
oxygen.
Animals of the rain forest
• Toco Toucan- largest of the toucans.
• Colored bright orange and black.
• Likes to live in open areas, lowland rain forest
and palm groves of south America.
• Live in flocks, in holes in trees
• They eat lizards, snakes, and
steal eggs from smaller birds.
Continued..
• Sumatran Rhinoceros- lives in the
Pockets of Indonesian and Malaysian rain forests.
• Smallest living rhinoceros.
• Their body length is from 8 to 8.5 feet and stands
4.5 feet from their shoulders.
• They prefer higher elevations, are found near
water and mud wallows.
• They eat wild mangoes, figs, fish, a variety of
plants, bamboo.
Continued…
• Slender Loris- are only found in
• the rain forests of India and Sri
Lanka.
• Can live in dry and wet forests but they prefer thick thorny
vegetation where they can escape predators and are easily
able to find food.
• Main diet are insects, but will eat flowers, leaves, shoots,
and sometimes eggs and nestlings.
• They eat a lot of bad smelling insects, they will wipe urine
over feet, face, and hands to avoid the sting of toxic insects.
• Only the size of a chipmunk.
• They live in trees and spend most of their time in them.
Plants of the rain forest
• Bengal Bamboo- can be found in the
Southeast Asian rainforest.
• It does very well in moist areas with
a lot of rain.
• It likes temperatures between 40 degrees Fahrenheit, and
100 degrees Fahrenheit.
• Can grow from anywhere to 40 to 80 feet in height.
• Very important to the environment they can reduce soil
erosion, sucks up water from heavy rains that may cause
flooding.
• They only flower once in their life time then die after they
bloom.
Continued..
• Jambu- grows naturally in southern India to eastern
Malaya.
• Jambu is a small tree or large shrub which grows 10 to
20 feet in height.
• They are pink when young and become light-green
above and yellowish-green beneath when mature.
• Jambu fruit can be white to a pinkish color, they are
very sweet and juicy.
• Considered poisonous.
Continued…
• Strangler figs- Most important plant of the rain
forest ecosystem.
• Numerous animal species feed on the fruit of the
fig tree.
• In some forests up to 70% of its animals depend
on figs for their diet.
• They are tall canopy trees which can grow to 148
feet in height.
• Kill the host tree that they are attached to.
Animal Adaptations
• Because there are so many animals in the rain forest
many have adapted to eating foods that no other
animal eat.
• Certain animals develop special features to help them
adapt to the environment for example the toucan
developed long, thick beaks to they can reach fruit on
trees, also to cut the fruit.
• Some animals use behavioral adaptions like the sloth,
they move very slow and hang upside down on trees,
also they grow green algae on their fur to make it more
difficult for predators to see them.
Plant adaptations
• Plants need to be able to adapt strategies to
find sunlight.
• Some plants attach themselves to other plants
so they can grow higher up and reach the
canopy, killing the host plant.
Human interactions
• Humans are logging a lot of the trees in the rain
forests for our needs like paper, and furniture.
• The rain forest is effected by water and air
pollution because of industrial operations and
activities.
• Poaching has made animal populations decrease.
• Products that are sold in America a lot of them
are made out of plants or trees in the rain forest,
making homes for animals, birds, and insects
disappear.
Interactions in the Rainforest
• Ants interact a lot with the plants in the rain
forest, the ants that live in the Macaranga tree
protect the tree from other plants growing on
it.
