Where Tropical Rainforests Are Found

Tropical Rainforests are found…(38%)Latin America Except Brazil: The Amazon, Central America,(25%)Southeast Asia & the Pacific Islands(19%)Brazil(18%)Africa: West Africa, Zaire basin, Congo basin, and eastern MadagascarTropical rainforests are mainly located in a band around the equator (Zero degrees latitude), mostly in the area between the Tropic of Cancer (23.5° N latitude) and the Tropic of Capricorn (23.5° S latitude).

A Map of Where They Are Found

The Physical Landscape

The TerrainMoss and other plantsRockstall, straight trees that don't branch out until

100 feet or more with smooth, thin barkhealthy, fertile soilgrassesrocky base because of small mountains and

hills covered by the rainforest.

Layers Of The Rainforest

The Emergent LayerThe emergent layer includes trees that

are usually spaced wide apart and range from 100-200ft tall with a special trait. these trees have umbrella shapes that grow tall over all other trees. The leaves on these trees are small and pointed because since they're so tall and grow above all other trees, exposing them to dry winds. The emergent trees also have very few branches with straight and smooth trunks and also have a very shallow root system.

The CanopyThe canopy layer form a type of room

over the understory and forest floor. The trees that make the canopy layer have large smooth leaves that come to a point. These many leaves of the canopy attracts more sunlight for photosynthesis which provides fruits, seeds, flowers, and leaves which supports a wide number of different animal life. The trees create good living conditions for wildlife such as snakes, toucans, and treefrogs, providing shelter from harsh weather.

The UnderstoryThe leaves of the understory block the

rest of the light that gets through the canopy from the forest floor. The huge broad leaves in the understory captures the light making it humid and dark which habitats a large amount of insect life.

The Forest FloorThe rainforest floor is relatively clear of

vegetation because of the darkness that the canopy causes. The canopy diverts the sunlight, and damps the wind and rain from reaching the floor of the rainforest. Despite its constant shade, the ground floor of the rainforest is the site for important interactions. Decomposition occurs on the forest floor, a process that is needed to preserve the rainforest. Thousands of plants and animals also live on the forest floor.

Human Influence

Human Influence Part 2Heavy deforestation often completely wipes out

rainforests.this deforestation often destroys species.it also drives climate change.Another effect is (supposed) global warming.People also create mining operations in rainforests which

require roads.These roads frighten the animals with the sounds created

by cars.agriculture also depletes the soil and because of the need

for new soil, people clear more of the rainforest.

Abiotic & Biotic Features

Abiotic helps some animals get shelter. Also some animals might hide there food between

rocks and more. Biotic helps by giving animals food and for

some animals shelter.

Food Chain #1

Food Chain #2

Decomposer Creatures such as the velvet worm are organisms that live on the forest floor

and feed off small invertebrates. Earthworms are another example of a tropical decomposer and feed off fallen leaves and tree bark.

Unlike worms, fungi are decomposers that can be found both on the forest floor as well as on the trunks of trees. Tropical fungi feed on decaying plant matter and are typically clustered into groups connected by an extensive root system.

Saprophytic bacteria are typically found ubiquitously in nutrient-rich soils. High numbers of these bacteria are found in tropical forests, with over 40 million bacteria residing in each gram of soil. These microscopic organisms feed on both dead plant and animal matter.

Arthropods, such as termites and ants, are common decomposers that, like fungi, can be found both on the forest floor and on trees. Termites specifically eat wood, while ants eat animals and fungi.

AdaptationsAnimals that hunt at night

When the sun goes down, some animals bed down. Others -- including the flying fox bat, the leopard cat and Wallace's

flying frog -- are bright-eyed and on the lookout for a meal. The adaptation to night hunting gives nocturnal animals the

benefit of reduced competition for food.

sizeLarge animals, like lions and elephants, live on the plains for good reason. Size is no advantage in the rain forest where a

dense understory makes movement difficult. Jaguars adapted with a small but stocky build that makes them

speedy hunters and small enough to sleep in trees.

Weather & ClimateRainforests are important because they help

maintain global weather patterns and rain. Water that evaporates from trees falls in

other areas as rain. They are lush and warm all year long! The average temperature of the tropical rainforest remains between 70 and

85° F.

PrecipitationThe yearly rainfall ranges from 80 to 400

inches (200 to 1000 cm), and it can rain hard. It can downpour as much as 2 inches (5 cm)

in an hour! Rainforests are extremely important because the water they produce is

evaporated and then used as rain in other areas.

Sunshine/Daylight TotalsTropical rainforests have an average

temperature of between 25 and 30 degrees Celsius during the 12 hours of daylight. However, only approximately 2 % of this

daylight hits the forest floor.

HumidityThe environment is pretty wet in tropical rain forests maintaining a high humidity of 70% to

80% year-round. Also, because Tropical rainforests are in the general area of the

equator, they are very humid environments

Air PressureAs air rises it cools and water condenses to form rain which is why the tropics are wet.

Air flows from high pressure to low pressure areas. This is why it rains so much in the

rainforest.

TemperaturesThe average temperature in tropical rainforests

ranges from 70 to 85°F (21 to 30°C).

Wind VelocityThe trees found in a tropical rainforest are primarily broad-leaved species that form a

dense canopy of foliage above the forest floor that acts as a wind buffer and decreases wind

speeds below the canopy. Even above the canopy most tropical rainforests experience minimal winds, a factor that contributes to

the overall hot and humid climate.

Weather PatternsWith rain almost every day, it means that it is

usually quite cloudy.

Month To Month Trends(Throughout The Year)

How do weather patterns impact the environment and

organisms in it?The damp and hot weather in the rainforest impact the environment because the plants have a lot of water, which makes it really

damp. The animals all have wather so they can survive. The plants and animals all need

to be able to adapt to the hot and damp weather in order to survive.
