- Im doing a project about tropical forest and I know nothing about it please help
Answer by Dancing Imu
The tropical rain forest is a forest of tall trees in a region of year-round warmth. An average of 50 to 260 inches (125 to 660 cm.) of rain falls yearly.
Rain forests belong to the tropical wet climate group. The temperature in a rain forest rarely gets higher than 93 F (34 C) or drops below 68 F (20 C); average humidity is between 77 and 88%; rainfall is often more than 100 inches a year. There is usually a brief season of less rain. In monsoonal areas, there is a real dry season. Almost all rain forests lie near the equator.
Rainforests now cover less than 6% of Earths land surface. Scientists estimate that more than half of all the worlds plant and animal species live in tropical rain forests. Tropical rainforests produce 40% of Earths oxygen.
A tropical rain forest has more kinds of trees than any other area in the world. Scientists have counted about 100 to 300 species in one 2 1/2-acre (1-hectare) area in South America. Seventy percent of the plants in the rainforest are trees.
About 1/4 of all the medicines we use come from rainforest plants. Curare comes from a tropical vine, and is used as an anesthetic and to relax muscles during surgery. Quinine, from the cinchona tree, is used to treat malaria. A person with lymphocytic leukemia has a 99% chance that the disease will go into remission because of the rosy periwinkle. More than 1,400 varieties of tropical plants are thought to be potential cures for cancer.
All tropical rain forests resemble one another in some ways. Many of the trees have straight trunks that dont branch out for 100 feet or more. There is no sense in growing branches below the canopy where there is little light. The majority of the trees have smooth, thin bark because there is no need to protect the them from water loss and freezing temperatures. It also makes it difficult for epiphytes and plant parasites to get a hold on the trunks. The bark of different species is so similar that it is difficult to identify a tree by its bark. Many trees can only be identified by their flowers.
Despite these differences, each of the three largest rainforests–the American, the African, and the Asian–has a different group of animal and plant species. Each rain forest has many species of monkeys, all of which differ from the species of the other two rain forests. In addition, different areas of the same rain forest may have different species. Many kinds of trees that grow in the mountains of the Amazon rain forest do not grow in the lowlands of that same forest.
Layers of the Rainforest
There are four very distinct layers of trees in a tropical rain forest. These layers have been identified as the emergent, upper canopy, understory, and forest floor.
Emergent trees are spaced wide apart, and are 100 to 240 feet tall with umbrella-shaped canopies that grow above the forest. Because emergent trees are exposed to drying winds, they tend to have small, pointed leaves. Some species lose their leaves during the brief dry season in monsoon rainforests. These giant trees have straight, smooth trunks with few branches. Their root system is very shallow, and to support their size they grow buttresses that can spread out to a distance of 30 feet.
The upper canopy of 60 to 130 foot trees allows light to be easily available at the top of this layer, but greatly reduced any light below it. Most of the rainforests animals live in the upper canopy. There is so much food available at this level that some animals never go down to the forest floor. The leaves have “drip spouts” that allows rain to run off. This keeps them dry and prevents mold and mildew from forming in the humid environment.
The understory, or lower canopy, consists of 60 foot trees. This layer is made up of the trunks of canopy trees, shrubs, plants and small trees. There is little air movement. As a result the humidity is constantly high. This level is in constant shade.
The forest floor is usually completely shaded, except where a canopy tree has fallen and created an opening. Most areas of the forest floor receive so little light that few bushes or herbs can grow there. As a result, a person can easily walk through most parts of a tropical rain forest. Less than 1 % of the light that strikes the top of the forest penetrates to the forest floor. The top soil is very thin and of poor quality. A lot of litter falls to the ground where it is quickly broken down by decomposers like termites, earthworms and fungi. The heat and humidity further help to break down the litter. This organic matter is then just as quickly absorbed by the trees shallow roots.

This is the bomb…
***Brownie Black Forest Trifle***
2 ounces (60 grams) unsweetened chocolate, coarsely chopped
1/2 cup (113 grams) unsalted butter, cut into pieces
1 cup (200 grams) granulated white sugar
2 large eggs
1/2 teaspoon pure vanilla extract
1/4 cup (35 grams) all-purpose flour
1/4 teaspoon salt
24 ounce (680 grams) jar of Morello Cherries in syrup
2 tablespoons Kirsch or Cherry Brandy
2 tablespoons (30 grams) white granulated sugar
1 1/2 cups (360 ml) heavy cream
1 1/2 tablespoons (25 grams) white granulated sugar
1/4 teaspoon pure vanilla extract
Shaved or grated semi-sweet or milk chocolate
Brownies: Preheat oven to 325 degrees F (165 degrees C) and place rack in center of oven. Butter and flour an 8 inch (20 cm) square baking pan.
Melt the chocolate and butter in a stainless steel bowl placed over a saucepan of simmering water. Remove from heat and stir in the sugar. Then stir in the vanilla extract and eggs. Finally, add the flour and salt.
Pour into the prepared pan and bake for about 30 minutes, or until a toothpick inserted in the center comes out clean. Remove from oven and let cool on a wire rack. When cooled, cut into 16 brownies.
Cherries: To make a sauce, drain the cherries, reserving the liquid. Place the liquid in a small saucepan, along with the Kirsch and sugar, and simmer for about five minutes or until the sauce is syrupy. Remove from heat and add the drained cherries. Let cool before making the trifles.
Whipped Cream: In the bowl of your electric mixer, or with a hand mixer, whip the cream, sugar, and vanilla extract until stiff peaks form.
To Assemble the Trifles: Take the brownies and cut them into small bite-sized pieces. Place a small handful of brownie pieces (about one brownie) in the bottom of each trifle glass. Next, place a spoonful of the cherries, and their juices, on top of the brownies. Place a large dollop of the whipped cream on top of the cherries. Repeat the layers, starting with the brownies. Cover and refrigerate for 4 to 24 hours to allow the flavors to mingle.
Just before serving sprinkle each trifle with grated or shaved chocolate and top with a cherry.
Makes 8 – 1 cup (240 ml) servings.
- I know Ive heard that name somewhere before, but I cant figure out where!?! Im hoping not though, because Id like to use Forest Lorn in a book Im writing. Have you ever heard of Forest Lorn from a book, movie, or anywhere? Please answer soon! Please and thank you!

idk it sounds familiar..
- okay see i have been doing research for 4 hours now on this topic!
And i am getting NOTHING out of it
the only information im getting is about – Temperate deciduous forests
but my project needs to be about Tropical deciduous forests
do you know anything about;
species – endangered?
i”m only getting temperate deciduous forests

- why are forest fires caused by people more likely to be extinguished by firefighters while those caused by lightning are often left to burn themselves out?
Answer by Cody
Forest fires serve a beneficial purpose in nature. They are a natural process and by allowing fires of “natural” cause like lightning to burn, we are allowing nature to run its normal processes. An area that experiences forest fires on a regular basis is a natural firebreak that regulates the expansion of other forest fires. If we extinguished all forest fires we would just be building the environment up for a huge uncontrollable forest fire. But we cant let every forest fire started by some idiot burn.
