Transcript of Rainforests!
-Most of the world's rainforests lie near the equator and have tropical climates.
- However, cooler rainforests exist in the Pacific Northwest region of the United States and Canada. -Rainforests host an extraordinary diversity of life.
-By some estimates, more than half of the Earth's original rainforests have already been burned or cut down for timber or grazing land, and more than 130 plant, animal, and insect species are thought to be going extinct daily as a result of the lost habitat. Life in the rainforest contains hundreds of animals. This varies from the smallest little insects to big gorillas. Life is spread out amongst different layers and areas.
Most insects and bugs live in the forest floor and understory layer.
Snakes and other such animals live on the forest floor.
Bee hives and nests are in the canopy layer.
Primates live from the forest floor to the Canopy Layer.
Scientists estimate that more than half of all the world's plant and animal species live in tropical rain forests. -Plant life in the rainforest biome has the largest variety of plants in the word. From microscopic fungi to sticks to huge willow trees.
-Plant life is contained at every layer of the rainforest.
-Plant life in the rainforest is a race to see who gets high first.
-Any trees that grow up to the emergent layer, don't let any sunlight to other plants under, in the canopy layer.
-Plant life on the forest floor has had to adapt to the lack of light. If you were to ever visit a rainforest, you would see patches patches of colorful plants and areas where there was only dirt. This happens because of something called focused light beam energy. Plants move over to areas where there are glimpses of sunlight, there fore making an area of plants.
-Plant life in the rainforest is quite fascinating, from the 750 tree species to 1500 species of flowers. Rainforests! Human Impacts (Threats) What can we do to help? The Divided Strata of a Rainforest: http://www.rainforestconcern.org/education_resources/what_can_we_do_to_stop_deforestation/ Bibliography! THINK BEFORE YOU BITE!
Next time you buy a hamburger from a fast food franchise, think about where the meat has come from! Many people consume a whole lot of meat which means that many animals are being killed everyday. Travelling
Try to walk or cycle to work or school instead of going in the car. If it is too far away to do this, then take public transport instead. This will save petrol, which is made from oil and comes from below the ground and so, like plastic, can cause the destruction of rainforests. You will also be reducing pollution and carbon dioxide emissions and therefore helping to combat global warming. Wood and timber - Are they rainforest friendly?
Once you start looking you'll be surprised at just how many wood products are made from rainforest trees such as mahogany or teak. In particular, a lot of our furniture is made from wood. Use of wood and timber cuts down on habitats of innocent creatures.

4. Growth in Population By:
-The world's largest rainforest is located in the Amazon River basin. The Amazon rainforest has been described as the "lungs of our planet" because it continuously recycles carbon dioxide into oxygen, with a significant percentage of the world's atmospheric oxygen being produced in this region.
-Scientists believe that as many as half of the Earth's different species of plants and animals are found only in the rainforests, which take up almost 7 percent of the world's landmass. Tropical Rainforests:
-located near the equator
-55% of all tropical rainforests are found in Latin America
-1/3 of the world's tropical rainforests are in Brazil
-Other tropical rainforests are located in Southeast Asia and the Pacific Islands
-Found along some coasts in temperate zones
-Largest temperate rainforests are found on the Pacific coast of North America
-Stretch from Oregon to Alaska for 1,200 miles
-Smaller temperate rainforests can be found on the southeast coast of Chile in South America
-Few other coastal strips with temperate rainforests, including small areas in the United Kingdom, Norway, Japan, New Zealand, and southern Australia. Tropical Humid HUMID! -In an average year in a tropical rain forest the climate is very hot and wet because of all the rainfall (250 ml).
-The rain forest has lots of rain because it is very humid.
-This climate is often found between the tropical Cancer and tropical Capricorn regions of the equator.
-Rain forests belong to the tropical wet climate group. RAIN! In the rainforests there is more direct sunlight approaching the land and sea there rather anywhere else. The sun warms the land and sea and the water evaporates into the air. The warm air can hold a lot of water vapor. As the air rises, it cools. That means it can hold less water vapor. Then as warm meets cold, condensation takes place and the vapor forms droplets, and clouds form. The clouds then produce rain. It rains more than ninety days a year and the strong sun usually shines between the storms. The water cycle repeats often along the equator. Rainfall is often more than 100 inches a year in the rainforest! PLANTS! The main plants in this biome are trees. A lot of the rain that falls on the rain forest never reaches the ground. It stays on the trees because the leaves act as a shield, and some rain never gets past the trees to the smaller plants and grounds below. Trees in this climate reach a height of more than 164 feet. They form a canopy. The forest floor is called understory. The canopy also keeps sunlight from reaching the plants in the understory. Between the canopy and understory is a lower canopy made up of smaller trees. These plants do receive some filtered sunlight.A tropical rain forest has more kinds of trees than any other area in the world. 70% of the plants in the rainforest are trees.About 1/4 of all the medicines we use come from rainforest plants. Many trees can only be identified by their flowers. Plant Life in

Information! What are they're Impacts? Ivy can make a thick mat of leaves that keeps sunlight from reaching native plants.
This dense mat can clog streams of water flow
Ivy can cover walls,trees and buildings. It is heavy for these structures to hold.
Trees can knock over! How do they spread? Seeds are mainly spread by birds and people.
Ivy can also spread by it's roots Basic Information! What are they're impacts? Dense patches of knotweed block people from getting into areas to fish,swim or boat!
Causes soil erosion because it's roots don't hold soil in place very well
Shades out native plant species which means animals don't have the plants to find food,build nests or find shelter!
Can block pathways like deer use How do they spread? Roots can grow up to 20m long!
Spread mostly by pieces of roots that get caught on trunks, or equipment.Roots can float through rivers
Even small pieces of root(1cm) can grow a plant! DOGS!
Dogs are a major cause of cassowary deaths, particularly in areas near residential development where dogs can attack and kill cassowaries when they wander into suburban areas seeking food or water. Basic Information! A cassowary is an invasive bird!
Also a flightless bird with glossy black plumage, a tall, brown casque (helmet) on top of its head, a vivid blue and purple neck, long drooping red wattles and amber eyes. http://cassowaryrecoveryteam.org/the-southern-cassowary/description/ The major threats to cassowaries are from the loss, fragmentation and modification of habitat, vehicle strikes, human interactions, dog attacks, pigs, disease, and catastrophic natural events. Food Chains & Food Webs Key Words: Producers: Any plant (often green)
Primary Consumers: This includes herbivores
Secondary Consumers: This includes carnivores How does the Climate affect plants? Conclusion: http://www.srl.caltech.edu/personnel/krubal/rainforest/Edit560s6/www/what.html The End:D??? Any Questions or Comments? Bio Accumulation! What does this mean? Process by which certain toxic substances (such as heavy metals) accumulate and keep on accumulating in living organisms, posing a threat to health, life, and to the environment. Also called bioconcentration, biological concentration, or biological magnification. In conclusion we all hope you learned about our biome! This assignment has been a great learning experience! We ourselves have learned a lot from this project and we hope you did too!

Definition... # 1 Pollution #2 Deforestration #3 Hunting #4 Growth in Population Severe air, water, and land pollution can cause the rainforest to die out because of a lack of positive growth elements. However, there are some trees in the rainforest that can process pollution into clean elements. The pollutions effect to rainforests destroys plants and animals, as well as the entire ecosystem. http://wiki.answers.com/Q/How_does_pollution_affect_rainforests Deforestation is clearing Earth's forests on a massive scale, often resulting in damage to the quality of the land. Forests still cover about 30 percent of the world’s land area.The world’s rain forests could completely vanish in a hundred years at the current rate of deforestation. http://environment.nationalgeographic.com/environment/global-warming/deforestation-overview/ Growing population needs the space and the trees are cut down because people need jobs and the wood can make a lot of money for lumbering companies. Unfortunately, even the people who depend on the rain forest are among the ones contributing to its decline. WE cut things down and kill things. We destroy the habitat of the animals and take away their food supply. Commercial hunting is reducing wildlife populations across the tropics and may be one of the gravest threats presently facing rainforests. When you kill a primary consumer it can affect the entire food chain. You might just think thats is on animal, but to the rainforests that one animal is very important. http://news.mongabay.com/2007/0430-hunting.html?ndxpg Food Web! Food Chain!
