In 1980, the estimated amount of rain forests in the world was 40, 000 square miles. This number decreases each year by roughly 1, 000 square miles due to construction and the resources being used for profit. It is too bad, because the rain forest is one of the most beautiful places on earth. It is the most diverse, containing the most species of living things, much more than anywhere else, and most have yet to be identified. All rain forests are located on earth’s “green belt”, that is, the area roughly around the equator that covers all the area from Mexico and the northern area of South America, to Africa, to India, stretching out to Indonesia, the northern tip of Australia and all the way to New Guinea.
This area is heavily covered with flora and fauna, and it abounds with life. In a rain forest, it is very wet and it rains everyday or every other day very heavily. There is a high and steady level of heat and moisture. There are some general layers to the rain forest. It starts 135 feet up in the air, with the lofty crowns of the tallest trees in the jungle. They take the most light, heat, rain and the most punishment from the winds.
Woodpeckers hunt insects in this layer, and also the black and white Colobus monkey can be found here, ready to launch into the air, using his specially developed tail as a rudder to guide his flight. Beneath this is the second layer of trees, whose crowns form a forest canopy. Rain filters through this canopy, and the top sides of the crowns hold a large amount of ferns and other small plants whose roots never touch soil. They live off the water and nutrients held in the small pockets of the leaves and branches. Tree frogs and chimpanzees live here, burrowing holes to live in the vast vegetation. The third layer is called the “understory.” This grows be neat the canopy.
The Essay on The Monteverde Rain Forest: A World Amongst The Clouds
Nestled atop Costa Rica’s continental divide, the Monteverde rainforest Proudly calls the town of Monteverde Its home. High above the coastal towns dotted Along the famous Costa Rican seaside, Monteverde sits at an altitude of 4,662 Ft. above sea level. Major Abiotic Factors Because of the high altitude, this particular rain forest is known as a Cloud Forest. A Cloud Forest is categorized as a ...
The gorilla makes this his regular hangout, also pythons lie here waiting for prey. The dim forest floor teems with life. Termites and ants feed on all the decomposing matter on the ground, and elephants make their way down a path of moss. Butterflies move silently by, and the air is still and very humid. These are the layers that make up the rain forest’s complex ecology.
In the rest of the essay I will describe some of the life forms found in the rain forest, and ways they affect the environment. In the rain forest, plants develop poisonous alkaloids to protect against insects, and insects develop complex digestive chemistry to overcome these poisons. Some of these plant alkaloids give native Indians great poisons for darts, and to cancer researchers hope for a new medicine. The rain forest root systems are so efficient that almost all of the nutrients in decaying plants are recycled into new ones.
Most roots are found within three inches of the surface in heavy clay or at the surface in sandy soils. Tiny rootlets grow up and attach themselves to leaves. When the leaf decays, minuscule fungi on the rootlets take over and send threadlike projections into the leaf which absorbs all of the leaf’s nutrient material. The phosphorous that the fungi produces is taken by the root, and in turn gives the fungus sugars from the tree. Al! so, termites and ants break down the forest litter. ALAM In a small lake in the middle of the rain forest, a small lizard skims across the water away from dangerous prey and attacks its own victim by surprise, yet another marvel of the tropical rain forest.
Mutualism occurs in the jungle with a specialized ant and a swollen-thorn acacia. The acacia provides budlike leaflet tips which are called Belgian bodies, which the ants give to their young for food. The insects hollow out the tree’s thorns when soft and green and raise their young inside. The acacia doesn’t have chemical defenses to repel dangerous and damaging insects and demands pure sunlight for proper growth. The ants patrol the tree day and night. If any insect lands on the tree, they bite it with a poisonous sting.
The Essay on My Forest
Forests are a treasure of tranquility, a symbol of integrity, source of diversity and a place of unity. We can find plenty of flora, fauna, trees, animals, birds and species living together with abounding love in the forest. Mixed fragrance, pure air, healthy herbals, roaring streams, descending falls and moving beings make a forest a lively playground of peace. Above all, its serene presence ...
They also attack plants that grow onto the tree, such as a vine. In this case, they would attack the vine at it’s base and pull it off the tree. There are also small leaf-cutting ants in the jungle that cut a portion of a leaf, bring it to their home, ! and chew it to a pulp and inject a body fluid to create a wet mulch. On this mulch grows the only food of this particular ant – a fungus that has only one species.
The mysterious part about this is that any spores that could develop on the mulch and contaminate it don’t develop. Paper wasps in the rain forest have to bail out their home after a heavy shower. They lap up a mouthful of water from the colony, and then spit it out onto the forest floor. They also coat the small stalk that attaches the nest to the branch of a tree with a sticky black secretion that repels some ants. But there are still some predators, such as jungle katydids which eat the leaves, and some species of ants that are not repelled by the black secretion. In one rain forest, there is a kind of toad that is voiceless.
So for the male to attract a mate, nature gave it a very noticeable characteristic – a fluorescent orange color, which is unmistakable. The females are blackish green with scale! t spots on them. In April and May, mating takes place. Where pools are formed on the forest floor by water trickling down trees, females lay around 200 eggs. After the males fertilize them, the embryos live in their aquatic world for about two weeks, then after that they hatch and mature. This species was discovered in 1964 and it helped win government protection for Monteverde, which is the place where these frogs can be found.
Biologist Jay M. Savage, amazed by the frogs, once wrote “I must confess… my… disbelief and suspicion that someone had dipped the examples in enamel paint.” There are other species of frogs, such as the green leaf frog, whose green body and glowing red eyes is an incredible sight.
The Term Paper on Benefits Of Forest Resources
A forest, also referred to as a wood or the woods, is an area with a high density of trees. As with cities, depending on various cultural definitions, what is considered a forest may vary significantly in size and have different classifications according to how and of what the forest is composed. A forest is usually an area filled with trees but any tall densely packed area of vegetation may be ...
They extrude and fertilize their eggs on a leaf over water. Young that are ready to leave their embryo drop into the water below. Also the poison-arrow frog is an interesting variety. The males battle for dominance and mates. Two can struggle for hours until one give up and croaks “uncle.” Their color warns predators of their composition which could prove toxic for snakes and other such beasts. The Dendrobates Granuliferus frog doesn’t have young that develop in water.
Instead, the tadpoles cling to the mother’s wet back. She transports them this way from place to place, usually depositing them in a cup of rainwater in a high branch safe from predators. She immerses herself in the water at first until the young let go of her body and swim into the water. ALAM A rare bird found only in rain forests, the quetzal, is a beautiful sight. They have long colorful tails which have long been worn by royalty of the Colombian Indians, who called the birds sacred.
It is beautiful animals like these that might start spur nations into preserving more of their rain forests, in hopes of keeping one of the most complex and interesting ecologies on earth.
