The forest is generally referred to as a primary producer, processing carbon into carbohydrates. All green plants, including those outside forests, are primary producers; it is often better to refer to the primary producers of the forest as the production ecosystem of the forest, or simply the production ecosystem. This allows us to distinguish it from other forest ecosystems. As leaves and twigs fall to the ground they build up a detritus of leaf mould which is sporadically added to by falling branches and trees, and by the decay of ferns, mosses, lichens, birds, insects and other ground dwellers.

Within this detritus there exists another forest community, the soil and litter community of decomposers which forms a distinct but vital ecosystem, the litter ecosystem, intimately linked with and supplementary to the production ecosystem itself. These two systems together formed the forest ecosystem, which can continue to function indefinitely only when these two systems are intact and fully functional. Other systems within the forest -including birds, insects and other forms of wildlife – are supplementary to the production and litter ecosystems.

The litter ecosystem consists of soil and forest to drivers together with its inhabitants. This assemblage of mostly tiny living things within the litter layer is vast and counts its population is in hundreds of thousands per hectare, for mites and small insects, and in billions for bacteria. It forms a recycling system returning into circulation vital substances used by living things as they die so that new life can use these again. This litter ecosystem is absolutely vital to the health and well-being of any forest. When it is destroyed by man or by other causes such as the trampling of animals the forest slowly dies.

Solar energy is the type of energy that is derived from sun light. It is one of the most environment friendly power sources available in the world. There are several environmental benefits of using solar power and the biggest advantage is that there are no carbon emissions from using solar energy. There is no air pollution and it is a renewable source of energy. More than being renewable it is abundantly available across the world. Also, it is more reliable natural source than wind.

While using wind energy is also a genuine cause to protect the environment, the installation and huge sized equipment tend to create a different type of pollution — noise pollution. If just one wind mill is located at a distance, one may not hear and feel the noise. However, if there are too many wind mills in one area, the noise levels will be much higher and can become a source of noise pollution. That is why people often prefer solar energy systems to wind energy systems.

Installation of solar power system is very simple and it does not take much space. It is not noisy and it is used just to absorb sunlight and convert it into electricity. It does not give out any toxic waste or poisonous gases. If a lot of people use solar energy, then the burning of coal, which is a fossil fuel, to generate electricity may come down rather significantly. This will help us to preserve the fossil fuels, reduce the carbon emissions and also downsize the progress of global warming.

Taking into consideration the numerous benefits, one can say without a doubt that the impact of solar power on the environment is actually a positive one. Today, the efficiency and dependability of solar energy is questioned. However, technology dealing with solar power is constantly improving and soon we may have a solution to both these questions.
