Saving these rainforest ecosystems and rehabilitating forest lands is critical to ensure clean air and a healthy environment for all. Tropical Rainforest Ecosystems An ecosystem is a community of living organisms, as well as the non living components in their environment, on whom they depend for their needs. Nutrients and energy that are obtained from the environment are used so as to maintain an ecosystem. An ecosystem consists of various species and each of them has a relationship with other species that cohabit the ecosystem. Ecosystems are of various types and are determined by the prevailing climatic conditions which in turn define the vegetation and the variety of life forms found there. Examples of ecosystems are rainforests, grasslands, deserts, and water ecosystems like marine or freshwater ecosystems. Ecosystems can be divided into their biotic or living components like primary producers that are green plants, herbivores, carnivores etc; and the abiotic or non living components like sunlight, temperature, moisture and so on. ...
The Amazon rainforest, also known as Amazonia is the largest rainforest in the world. It is sometimes referred to as the lungs of the planet, due to its capacity to recycle large quantities of carbon dioxide into oxygen. Situated in South America, the Amazon rainforest covers more than half of Brazil and is the drainage basin for the Amazon river and its tributaries. Its proximity to the equator ensures plenty of heat and sunlight, which in turn generates rain that provides the moisture. High temperatures, and abundant rainfall throughout the year, results in a climate that is warm and humid. These are ideal conditions for the growth of all types of vegetation including a wide variety of trees, plants shrubs and other vegetation, which attracts innumerable birds, insects and animals. Hence rainforests are rich in their biological diversity and home to myriads of animal, bird and insect species. Biodiversity is important to the environment because it increases productivity in an ecosystem, where every species, no matter how tiny, contributes to the health and well being of the ecosystem. As Ban Ki Moon (2010) rightly points out “Biodiversity underpins the functioning of the ecosystems on which we depend for food and fresh water, health and recreation, and protection from natural disasters.” (Ban Ki Moon, 2010) The Amazon rainforest consists of four layers, the emergent layer, the canopy, the shrub layer and the forest floor. The emergent layer consists of the tallest trees, some that are over 50 meters in height. The leaves of these trees are smooth and waxy and taper to what is known as a drip tip to allow water to drip off it to the layer below. The canopy is below the emergent layer and is a sea of leaves. Since the tallest trees and the canopy of

By definition, heavy metals have a density of 5.0/gcm3 or more which is much heavier than the density of an average soil particle. They occur naturally in rocks but their concentrations are regularly augmented due to contamination and pollution. The most common heavy metals with respect to possible hazards are mercury, lead and cadmium and chromium.
Since the inception of the modern era, the ratio of humans to plants and animals has been ever increasing because of various factors addressing population explosion and the inability for humans to control the same. However, this is no excuse to give up protecting plant and animal life since humans depend on the same for more than one aspect of their sustenance.
The park comprises biotic factors, such as native forest plants, birds, insects and decomposers, whereas abiotic factors include stones, soil, dead tree logs, and minerals in the soil (Nadakavukaren, 2011). The ecological dormant in Hyde Park are the native forests which constitute the greatest biomass in the micro-ecosystem.
Abiotic components comprise of chemical and physical things present in an environment. Biotic components comprise of the living things, for instance; plants and animals. Joshua Tree National Park is an example of a natural ecosystem that supports the existence of a variety of rare trees, as the name suggests, and a variety of wildlife.
The succession progress is shown below.
The whole process is a "sere". And each successional stage is a "seral stage". Seral stages may be a few years or a few hundred years in length depending on type of stage and environment conditions. The final or equilibrium stage is known as "climax community."
The United Nations has grouped the ecosystem services in four categories which include; provisioning, which is the production of water and food, cultural which are the recreational and spiritual benefits, supporting which include crop pollination and nutrient cycles
Ecosystem services, therefore, refers to the processes by which the environment avails the resources exploited by human beings either for direct consumption (such as air and water) or for the production of goods and services used by man (Wilson 307). The
When it comes to the action of human societies it is clearly visible that the human beings are ignorantly reacting to the nature. The main aspect is the way in which they pollute the natural resources with no second thoughts. However a small percentage of humans in the form of scientists, corporate bodies and social activists work towards protection of ecosystem services.
