Tropical rainforests are an extremely unique and diverse ecosystem that are located around the earth’s equator. They once covered roughly 7% of the world, but due to human encroachment that has dwindled to just 2%. It is a highly moisture rich environment that typically receives anywhere between 60 and 400 inches of rainfall annually and average humidity ranges from 70 to 90%. A high average year round temperature, coupled with the moisture rich environment, creates an ecosystem that allows for a level of biodiversity seen nowhere else on the planet. This also results in a specific type of layering design that allows the system to survive and recycle its nutrients.
The top layers are called the canopy and the emergent layer and they for the largest percentage of biodiversity. Rainforests account for almost 50% of all biodiversity on the planet and almost 90% of that is contained in the upper portions. The large trees are interconnected through a series of vines that act as a road system and it allows the various insects and animals to travel freely throughout the canopy. The treetops are a dense network of large, leafy coverings that allow very little sunlight to leak through to the forest floor. The abundant sunlight at this layer creates a very rich resource abundance that supports the many organisms that make it their home. This also means that plants other than trees are forced to adapt in order to flourish in the light deprived environment below the canopy.
The lower levels of plants exist in a layering system that is dictated by their sunlight needs. Leaves on these plants are large and broad to allow the absorption of the limited sunlight. The ground level here contains very little plant litter when compared to...

...he use of smaller shipping roads by logging companies can also reduce their negative footprint in these areas. Tree plantations can help to restore areas already devastated by logging operations. Governments and organizations need to shift their mindset to see reforestation efforts as an investment in their future.
While tropical rainforests account for a relatively small percentage of land acreage, their benefits to the rest of the world are boundless. The loss of these benefits will continue to increase unless drastic changes are made. Every ecosystem is intertwined and when one begins to decline it will only lead to a decline of the others. Preservation and restoration of tropical rainforests are of the utmost importance in terms of slowing, and potentially reversing, the negative effects of climate change caused by the loss of the earth’s natural resources.

My Personal Niche Of A Botanist Studying Endangered Plants Within A Tropical Rain Forest

- Every species has a unique ecosystem in which it lives. In order to survive, the habitat is where the organisms’ survival needs of food, water, shelter and place to breed is met. According to our reading this week, habitats and niche are terms used to discuss the interaction of individual organisms in populations, and groups of organisms in communities and ecosystems including humans because we are organisms living in the ecosystem also. (Ireland, K. 2013). Each living thing has their own specific habitat and niche, where they live and how their job contributes to their habitat....   [tags: Rainforest, Forest, Tropical rainforest, Life]

Essay on Importance of Mangrove Ecosystem

- What is the Mangrove Ecosystem. Mangroves are found in tropical and sub-tropical areas which located at intertidal areas and estuary mouths between land and sea. There are consists a group of plant growing in shallow and muddy salt water or brackish waters. The specific regions where the plants occur are called “mangrove ecosystem”. Mangroves provide critical habitat for a diverse marine and terrestrial flora and fauna. The continuous interruption of physiological and morphological stresses, salinity effect, aeration and onslaught of wave action in long term period are causes of the ecosystem highly fragile (source?)....   [tags: Ecology ]

Coral Reefs: A Diverse Ecosystem Essay

- Coral reefs are one of the oldest and the most diverse ecosystems in the planet; because of such matter, scientists coined coral reefs as ‘rainforests of the sea. The National Oceanic and Atmospheric Administration or NOAA for short (2008) estimated that about 25% of marine life use coral reefs as safe havens from predators, breeding grounds, and feeding grounds despite the fact that coral reefs only cover a small percentage (estimated about 0.1%) of the world’s oceans. It serves an umbrella specie because it serves both as a habitat and a living, breathing organism for other marine animals to thrive....   [tags: coral reefs, ecosystem, marine life]

Essay on The Ecosystems And Evolution Of Tropical Forests

- Chapters 3-4 Ecosystems and Evolution 1. Even though tropical rain forests only cover about 2% of the earth’s land surface, they are home to about half of all terrestrial plant and animal species. By continuing our harmful logging practices and ever-increasing fossil fuel consumption, we are becoming a greater threat to these “endangered” ecosystems. These tropical rainforests are important in that the copious trees take in carbon dioxide and help regulate its levels in the atmosphere, which is important in keeping our air at the right temperature....   [tags: Water, Water cycle, Plant, Precipitation]

Essay about The Link Between Ecosystem Services And Biodiversity

- I think that high biodiversity is necessary for maintaining various ecosystem functions and services because when diversity allows for functions and services to take place. For example, in an ecosystem where there is less diverse, the organisms in that community are more susceptible to disease and are less resilient to disasters. Therefore, when there is less diversity the community will be less likely to be proactive in the community for functions like decomposition and nutrient cycling. Also, more diverse communities are more likely to include organisms that are very efficient at doing certain functions....   [tags: Biodiversity, Ecosystem, Endangered species]
