Science Biome Project - Tropical Rainforest
Transcript of Science Biome Project - Tropical Rainforest
-they climb tree trunks into the canopy where there is more sunlight.
-they grow on tall trees to reach sunlight.
-they absorb most of the sunlight and have leaves with narrow tips that allow rain to run off quickly, therefore the weight on the branches is reduced.
-they are adapted to the understory of the forest.
•Plants in general have many layers. What are the native plants
and their adaptations to live there Many native animals in the tropical rainforest are adapted to live in trees because there is little vegetation on forest floor and many are specialists (organisms adapted to a particular food or habitat which reduce competition).
•Parrots and toucans
-they use their strong big beaks to cut nuts from trees and crack open the tough shells.
-they have a low-calorie diet of leaves which makes them less noticeable to predators like jaguars.
-they climb tall trees and cut small pieces of leaves to bring back to their nest to bury the leaf along with the ant’s saliva.By doing this, it causes the growth of fungus and the ants eat the fungus.
•Monkeys and apes
-they have long arms to swing on trees which helps them avoid the predators at the ground What are the native animals and their adaptations to live there Where is it

-An example of mutualism would be sloths and algae.The sloth's hairs are grooved, which allows algae to easily take hold and grow on the sloth's fur. This camouflages the sloth and allows the algae to get closer to the sunlight. Commensalism Parasitism Mutualism -An example of commensalism would be vermiliads (plants living on trees in tropical rainforests) and frogs; the frogs get shelter and water from the vermiliad but the vermiliad is unaffected. -An example of parasitism would be ticks and monkeys. Monkeys carry ticks which feed on their blood. Weather Report The average precipitation in tropical rainforests is approximately 250 cm per year. What is the average precipitation? What is the average temperature? As you can see from the climatograph, tropical rainforests are warm, wet forests with many tall trees. The average temperature is around 20C to 25C year-round. The Tropical Rainforest Biome Recreational Activities Some recreational activities are .... -kayaking, archery, sport activities, pony rides, nature walks, waterfall visits, domestic farming, fruit farming, night walks, fishing, and river boat rides. What are some other biomes nearby other biomes nearby for side trips are.... Deserts What is the weather like in the tropical rainforest biome WARNINGS ! Threats to the Biome: Logging (when large areas of forests are cleared they can not evaporate as much water through transpiration (the process by which water evaporates from the leaves and is replaced by water drawn up from the ground through the roots and the stem).
Industrialized agriculture (In many areas of rainforest, agriculture can be supported only for a few seasons after the forest is cut before the nutrients are depleted. In addition, some tropical rainforest soils undergo a physical transformation when exposed to heat and sun; they bake into an almost solid surface that is unsuitable for plant growth.)
Power plants and other industries cut and burn trees to generate electricity.
The paper industry turns huge tracts of rain forest trees into pulp.
The cattle industry uses slash-and-burn techniques to clear ranch land.
Agricultural interests, particularly the soy industry, clear forests for cropland.
Subsistence farmers slash-and-burn rain forest for firewood and to make room for crops and grazing lands.
Mining operations clear forest to build roads and dig mines.
Governments and industry clear-cut forests to make way for service and transit roads.
Hydroelectric projects flood acres of rain forest
Sustainable-logging regimes that selectively cull trees rather than clear-cut them would save millions of acres of rain forest every year.
Campaigns that educate people about the destruction caused by rain forest timber and encourage purchasing of sustainable rain forest products could drive demand down enough to slow deforestation.
Encouraging people who live near rain forests to harvest its bounty (nuts, fruits, medicines) rather than clear-cutting it for farmland would save million of acres.
Government moratoriums on road building and large infrastructure projects in the rain forest would save many acres. Solutions: The golden lion tamarind or golden marmoset is one of the most endangered animals in the world. The tamarind monkey is nearly extinct because of its strawberry-blond fur, which poachers can sell in the black market for close to $20,000. Golden Lion Tamarind Monkey Endangered Species Gorilla About 80 percent of the gorilla population has become extinct. Gorillas are found primarily in the West Central Africa rain forests. Gorillas face threats from hunters, change in quality of habitat and diseases, such as the Ebola virus. The magnificent jaguar cat is facing complete extinction. Jaguars are threatened by poachers who hunt the cat and the destruction of its rain forest habitat. Jaguar The orangutan's population has declined approximately 80 percent in the last 75 years. Destruction of habitat, hunting and commercial trapping for the wild animal trade have led to the orangutan's near extinction. Orangutan Toucans are mostly found in the rain forests of Central and South America. Many of its 40 different species are endangered. Toucans are threatened by habitat loss and capture for commercial pet markets. Toucan Gear/supplies you should bring * Rain gear

For many years, it was thought that tropical rainforests were essentially unaffected by climate change Now studies are showing that not only were they changed during past events like ice ages, but some areas are being affected right now by warming. At Monteverdi Cloud Forest Reserve, Costa Rica, clouds are forming higher, drying out some of the habitat and causing changes in flora and fauna.
Lengthening dry periods could drive some species into extinction.
Central and South America: Climate change could alter about two-thirds of the rainforest's biodiversity — the variety and abundance of plants and animals in an ecosystem. Many climate models predict that droughts may become more frequent and severe here as greenhouse gases build up in the atmosphere. Combining that scenario with current patterns of land-use change, the Amazon Basin alone could see changes in biodiversity over 80 percent of the region.
The Congo: Logging and climate change could harm between 35 percent and 74 percent of the forests in the region, and about 70 percent of Africa's tropical forest biodiversity continent-wide.
Asia and the central and southern Pacific islands: Deforestation and logging — which has dropped by more than 22 percent in the last decade — puts between 60 percent and 77 percent of the area at risk of biodiversity losses.

http://kids.mongabay.com/elementary/401.html Google.ca Tropical rainforests house around half the world's plant and animal species.
-Some are near scenic mountain ranges, others surround giant lowland rivers, While some are found near beautiful beaches and coral reefs.
Tropical rainforests offer opportunities for cultural exchange, photography, adventure, fishing, hiking, relaxation, birding, and wildlife spotting. Biome Rainforest Tropical THE BY: Maria Tabud, Monique Tang, Caitlyn Gatus, Alycia Tran A NEED place You,
