    Sulayman Jagne Gambia The sources of energy for many process occurring in this earth surface come from the sun, so this mean the sun radiating as many important role in the earth's movement and give energy to many life like plant an animals as well. The sun radiation has another important factor even in the atmosphere and ocean current. this topic is notifying the importance the sun have indirect or direct in life cycle f all living organism

    Helen Goldsmith Australia It is amazing how little we utilize the energy of the sun. Countries around the world are making great steps toward sustainability with huge success. I feel it is a matter of time (and not much time at that) before the world moves toward sustainability in a monumental way.

      Muhammad Abbas Pakistan There will be uncountable benefits of utilizing solar energy,,only these are few ones which are accessible to humen being and new uses are arising day by day ,so we can say that nd possible in future that everthing will b running with solar energy ,so we will have neet and clean environment

    Mark Bell United Kingdom One cycling of energy is that the plants and animals we eat are all created or sustained by solar energy i.e plants from photosynthesis and the fact that animals eat the plants. Food intake that animals and humans intake has a waste bio product in the form of excrement which in turn can be used as a chemical energiser for plants in the form of fertilizer which completes the full circle of cycling energy.

    Mark Bell United Kingdom The most basic production of energy is the food we eat which gives us energy in the form of calories. However the food we eat is processed by chemical energy in the soil and solar energy from the sun (photosynthesis)

    Mark Bell United Kingdom Do you think we should pursue primary energy in the natural forms of wind and water as they have very little by way of an energy sink?.

    Mark Bell United Kingdom In a way the heat that we get from the sun can be be classed as an energy sink as it is a secondary energy from nuclear fusion, but we reuse it in the form of solar power.

    Mark Bell United Kingdom Do you believe that fossil fuels are more frequently used because of their basic function of "collect", "burn" producing heat energy as opposed to solar , wind and water power require more human innovation to produce energy?.

    Mark Bell United Kingdom I believe more emphasis and exploration into renewable energy such as solar, water and wind power which will have less impact on the environment as opposed to the more carbon based energy sources such as oil, gas and coal which require , in the main combusting to produce energy which in turn creates pollutants.

    Christina Morgan United States of America I think we need to explore and expand all options for energy including waste to energy

    Gaurav Kumar Pathak India The energy is very important for the development of a country and not only of a country, is important for the development to humans, plants and animals, but in this moment is very important knowing that the earth offers diferent types of energy for that the humans develop all our activities and so have a good relationship with the earth with the environment, having like a rule a sustainable development.

    Xtopher Bisong Nigeria for food and other animals eat the animals that eat plants. Either way, they are “consumers.” Some organisms, such as fungi and bacteria, break down dead organisms (both plants or plants parts and animals) and therefore operate as “decomposers.” Decomposition eventually restores (recycles) some materials back to the soil for plants to use. Organisms can survive only in environments in which their particular needs are met. A healthy ecosystem is one in which multiple species of different types are each able to meet their needs in a relatively stable web of life. Newly introduced species can damage the balance of an ecosystem.
