Biofuels Biofuels are Fuels made from Biomass Biofuels are made from plants‚animals‚ or their waste products. Here I have listed three examples of biofuels beneath. 1 Micro-organisms decompose waste materials to produce biogas. 2 Biogas is usually about 70% methane and somewhere between 20 and 30 % carbon dioxide 3 the way we use it to generate energy is to burn it to heat up water which will then turn a turbine to produce electricity. It is also heard of to heat the water to steam which

Observing Ecosystems Ecosystems-The sums of all the organisms living within its boundaries and all the abiotic factors with which they interact. Chemical Elements such as carbon and Nitrogen are cycled among abiotic and biotic components of the ecosystem. Photosynthetic organisms assimilate these elements in inorganic form from the air‚ soil‚ and water and incorporate them into their biomass‚ some of which is consumed by animals. Both energy and matter are transformed in ecosystems throught
