Transcript of Abiotic Factors & Biotic Factors of the Tropical Rain Forest

Abiotic And Biotic Factors of the Tropical Rainforests Primates This is an Abiotic Factor of the Tropical Rainforest!
Honestly, this is my favorite part of the Prezi because
primates are my favorite animals! The important role for
these magnificent creatures is that they separate seeds.
The Aye-Aye They're nocturnal feeders so that they can avoid
predators during the day. Large eyes allow more light
in at night. They build their nests at the top of
canopies. They have extremely large middle fingers to
reach within tree trunks. This is also another biotic factor. Birds I may be scared of birds but they do help out in their
ecosystem by dispersing seeds and squashing fruits.
There are about 40 different kinds of toucans in
existence! In most people's opinions, toucans are the
most beautiful birds in the world because of its
extravagant colors. This also another biotic factor. Buttresses Since the rainforests' soil is too thin, believe it or not, the buttresses roots keep all the other trees roots' in the forest up. For people who live in the jungle, they use buttresses roots to communicate amongst each other by banging long wooden sticks on them. Buttresses trunks' grow up to 15 feet above sea level! Wow that's tall, well at least for a trunk that is! This is also another biotic factor.
Pitcher Plants They feed on insects to make up the lack of nutrients in
the soil where they live. These plants are by far carnivores. They
are one the 600 species of carnivorous plants and they have all
evolved by independently eating insects. Another word for them
would be insectivorous plants. They also provide food for insects that pollinate other plants. Pitcher plants are endangered so it is illegal to pick them from the wild only if you're a collector or gardener then you'd have to purchase them. This is another biotic factor.

Overall Climate The climate, year around, is very humid but hot. The reason why it's humid is because of the rainfall, which is 250 cm averaged, and why it's hot is because of the location. What it does is that the air holds warm vapor and goes everywhere in the air. The annual precipitation is over 150 cm. In this climate trees grow up over 164 feet which form canopies. The plants that make up the area have eventually adapted to the small amount of sunlight they get. This an abiotic factor. Soil Over two-thirds of the world's rainforests are considered
wet deserts known for its reddish-yellowish clay-like soil. Many of tropical soils are very old and impoverished where there has been no recent volcanic activity to make up new nutrients. Under these conditions, many have wondered how these soils can hold up such vigorous amount of plants. Which it's supported by buttresses roots but I already said that. This is an abiotic factor. Sunlight The sun helps give light, warmth, and the ability to survive on Earth. The light helps us see and the warmth keeps us healthy and alive. The sun helps producers, such as plants, to make their food which provides them with energy and when we eat the carriers we get energy. Rocks Chemical Weathering- When the atmosphere and the rocks come together and the warm vapor weathers down the rocks. All rain water is slightly acidic so the carbon dioxide, vapor, and rock all come together for chemical weathering.
Biological Weathering- The biological weathering is primarily of the physical sort. The rainforests' rocks are mostly weathered biologically. Animals and humans play roles in weathering, for example, when animals burrow in the ground that is weathering biologically.

Water This is one of the most visible abiotic factors. The average humidity in this region is 77-88%. As a result, under the top canopy layer is extremely humid.
