The Role Of Tropical Rainforest And Water Cycle - 1604 Words

The role of tropical rainforest in water cycle The tropical rainforest plays a significant role in regulating the water cycle on earth, through transpiration and evaporation process. Transpiration is the water vapour loss from plants through stomata, and evaporation is the water loss from all other part of plants but leaves and other living things in the forest. Evapotranspiration are the accumulation of transpiration and evaporation in the forest. During transpiration, trees suck water from soil through the root system and transport the water to leaves through xylem, and then release the water to the air through stomata. Transpiration happens simultaneously with photosynthesis. The soil loss water due to evapotranspiration process and the water level will be recharged through precipitation. In the tropical rainforest, precipitation rate are high due to high evapotranspiration rate. High evapotranspiration rate plays a significant role in cloud formation above the rainforest area and its surroundings. Water vapour that is released into the air will be condensed as it moves to a higher altitude. The condensed water vapour form the clouds above the forest. The more water vapour being released into the air, the more clouds would be formed. Figure 1.

Albedo is the fraction of solar energy reflected from theShow MoreRelatedA Community Of Organisms With Their Environment1327 Words   |  6 Pagesthere are many ways for organisms to get energy and food. In an ecosystem there are three cycles that circulates nutrients needed within an ecosystem. The three cycles are the nitrogen, water, and carbon cycle, and they all play a major role in an ecosystem. Without them, there wouldn’t be any life on Earth. Also, every organism needs oxygen, water, carbon, and nitrogen in order to survive. The nitrogen cycle is the process where nitrogen is converted between various chemical forms. The transformationRead More The Rainforest and Deforestataion Essay1099 Words   |  5 PagesWHY ARE RAINFORESTS IMPORTANT? Rainforests are important to the global ecosystem. Rainforests: ? provide a home to many plants and animals, ? help stabilize the worlds climate, ? protect against flood, drought, and erosion, ? are a source for medicines and foods, ? support tribal people, and ? are an interesting place to visit RAINFORESTS HELP STABILIZE CLIMATE Rainforests help stabilize the worlds climate by absorbing carbon dioxide from the atmosphere. Excess carbon dioxideRead MoreGlobal Environmental Issue : Deforestation Essay1103 Words   |  5 PagesGlobal Environmental Issue: Deforestation Deforestation is a global environmental threat the planet is currently experiencing. Deforestation in tropical rainforests is especially problematic as they are home to a myriad of important plant and animal species. The rich biodiversity found in these environments are needed, as we rely heavily on the ecological services they provide for us. Forest exports, cattle ranching, and international corporations and agencies are a few factors and actors to thisRead MoreDeforestation Effects On Amazon Forest Resilience1725 Words   |  7 PagesDeforestation is negatively affecting the interaction between the water cycle, soil sustainability, and trees stability. There is a chain reaction due to deforestation. Deforestation leads to decrease in biotic pump disrupting the water cycle leading to a decrease in transpiration and increase in temperature. Such rise in temperature leads to lack of rainfall to the forest and increase droughts and forest fires to which fires will disrupt the water cycle even more. Deforestation effects on Amazon forest resilienceRead MoreEssay on Ending Destruction of the Rainforest1339 Words   |  6 PagesEnding Destruction of the Rainforest As destruction of the rainforest continues, man slowly paves the inevitable path to a clear end. It has been known that the rainforest is an essential provider for the balance of the mother earth and that it acts as a key for life as we know it. Yet, the world still decides to quietly watch the disappearance. In fact, most people realize what exactly is taking place. But however, instead of trying to aid in the termination of this disaster. They placeRead More Environment and Climate Change in Panama Essay1521 Words   |  7 PagesEnvironment and Climate Change in Panama Home to vast tropical rainforests, an immense variety of animal and plant species and the seaway that connects the North Atlantic Ocean and the North Pacific Ocean, Panama relies heavily on all these resources for its economy. However, environmental challenges threaten the sustainability of these assets and therefore create a significant problem for the country. This paper will examine the effect of weather and climate change on PanamaRead MoreDeforestation Is A World Without Trees?1486 Words   |  6 Pagesof the world’s rainforests have been destroyed in the last 10,000 years or so,† according to the World Wild Life Fund (WWF). The majority of this loss has happened in the last 50 years, occurring simultaneously with a massive increase in the human population. Deforestation is hurting our earth, and therefore, we must demand for stricter laws to prohibit and restrict companies and corporations from destroying large amounts of our earth’s rainfo rest before it is too late.

Rainforests now cover less than 6% of the Earth’s surface, scientist estimate that more than 50% of all the known plants and animal species live in rainforests. Rainforests also produce 40% of the Earth’s oxygen and play an important role in the ecosystems. Australia has approximately 4.2 million hectares (o.5% of Australia’s landmass) of lush rainforests. The rainforests are distributed evenly, extendingRead MoreEssay on Reasons for the Expansion of Deforestation590 Words   |  3 Pagesmore people we are, the more we need to make new cities, the more we need to build more houses and establishments and the more land we will need. Desertification of land, and mining release some type of toxic chemical that will contaminate the rainforest making it unsuitable for trees to grow. (Deforestation, n.d.).Overall you environmentalists may have noticed how deforestation is done intentionally because out of deforestation all the industries gain money, which is one of the main reasonsRead Moretropical rainforest Essay5226 Words   |  21 Pagesï » ¿3.1.1. Why does life thrive in the tropical rainforest? The tropical rainforest is very rich in water and food thus life thrives. We all know that food and water are the things that animals need the most for their survival. It also has a warm temperature due to the constant energy that the sun provides. The plants need the sunlight for the process of photosynthesis to be completed and use it to derived energy. And the plants serve as the food for some animals and these animals serve as the food
