Transcript of tropical rainforest
lots of precipitation Lots of rain Heavy precipatation Up to 30 cm of precipitation each month during winter time (Dec. to Mar.) As you can see, the rainforest has millions of different species. Each of them is an important part of the food chain. The tropical rainforest is divided into five layers: An example of commensalism: An orchid living on a tree. An example of mutualism: A hummingbird and dianthus. An example of parasitism: A vampire bat feeding off the blood of a hog. approx. 20 cm of rainfall during the summer time (Jun. to Sep.) Here are some examples of Common animals found in tropical rainforest: Jaguar Snake Frog Bat Bird Common Plants found in tropical rainforest: Epiphyte Canopy Level Trees Understory Vegetations Vines Flowering Plants Biotic components of the tropical rainforest: Abiotic components of the tropical rainforest: Some those animals lives together in
peace and some of them live off others The forest is divided into two big parts: They are divided into two seasons A example of a specie
at the top of the food chain Animals Plants Fungi and other microscopic organisms Climatograph of The red line shows the average temperature per month the green bars show the average rainfall per month Flowers Soil Water Sunlight Temperature Humidity Nitrogen Oxygen Tropical Rainforest are mostly found in the regions of: Central and Western Eastern Madagascar and Southeast Asia around the equator, between the Tropic of Cancer and Capricorn. Biotic and Abiotic Although at top of the food chain,
they are at the bottom of the energy
dipersion Plants get 100% of the energy primary consumers gets 10% Some carnvores and omnivores gets 1% Poor guy gets only 0.1% of the initial energy Those are examples
of animals that has
adapted to survive Mimicry, this frog conseals
itself in green Poison to warn the predators While most plants competes in height to get sunshine, this guy here catched insects to obtain nutrients Anacondas can swim, and the forest is full of rivers Adapted to hunt at night
reduces competition and
heat Adapted to climb where some
predators have no access to An example of a competitive predator-prey relationship: The anaconda predates on the caiman and the capybara; however, the anaconda also predates on the caiman. But they can never adapt to this This is easy as... 1 2 3 Therefore, the anaconda and the caiman are in a competitive predator-prey relationship. Deforestation is the biggest problem that the rainforest is facing. Consequences that deforestation of tropical rainforest can bring about: Extinction of many organisms living in the tropical rain forest biome. Ecological and enviromental crisis such as: massive flooding degradation of water qualities And most serious of all, climate change involving the release of CO2, a.k.a. global warming. Humans have heavily deforested much of the tropical rainforest for the following purposes: Road building Building houses Logging Cattle ranching and commercial agriculture We can work together to save the rainforest, to stop further deforestation, and preserve the rich biodiversity that the tropical rainforest has to offer. "The worst thing that can happen during the 1980s is not energy depletion, economic collapses, limited nuclear war, or conquest by a totalitarian government. As terrible as these catastrophes would be for us, they can be repaired within a few generations. The one process ongoing in the 1980s that will take millions of years to correct is the loss of genetic and species diversity by the destruction of natural habitats. This is the folly that our descendants are least likely to forgive us for." — biologist Edward O. Wilson However, it has been identified that the renewable resources that the tropical rainforest generates is far more valuable than the value of the logs and other non-renewable resources that are drained from the land in the long run. Mining The tropical rainforest has the greatest biodiversity on Earth. Destroying this biome would mean the loss of many important organisms on Earth. Work Cited
animal adaption rainforest Here's an excerpt from www.rain-tree.com stating how we can profit more from the renewable resources of the rainforest rather than the lumber and cattle ranches. "...the latest statistics prove that rainforest land converted to cattle operations yields the landowner $60 per acre; if timber is harvested, the land is worth $400 per acre. However, if medicinal plants, fruits, nuts, rubber, chocolate, and other renewable and sustainable resources are harvested, the land will yield the landowner $2,400 per acre. This value provides an income not only today, but year after year - for generations. These sustainable resources - not the trees - are the true wealth of the rainforest..." http://lehighvalley.psu.edu/biodiversity/defined/images/climos-troprainforest.gif

http://www.youtube.com/watch?v=6nuz0ALUbgE Thank You for Watching! 5 questions for review purposes:
1. Name the continents where tropical rainforests are present.
2. Which time of the year are the wet seasons?
3. Name two animals and two plants living in tropical rainforest.
4. Give an example of mutualism, commensalism, parasitism, and competitive predator-prey relationship in the tropical rainforest.
5. What are the threat to tropical rainforests; why should we conserve tropical rainforests, and how can we do so?
