The rainforest consists of several layers. Each layer has plants and animals which are adapted to the conditions found there. In the ground layer, soil is poor and any nutrients are quickly recycled. The next layer is made up of shrubs and plants which can tolerate low light levels. The lush undercanopy consists of smaller trees which compete for the light and space. Epiphytes are found in the undercanopy.
In additon. biofuels may be marketed as good, renewable, sustainable or next generation, partly for promotional purposes. So achieving a widely accepted definition of advanced and/or sustainable biofuels is a challenge. Often the term is applied to biofuels produced from lignocellulosic (LC) or cellulosic biomass.io-oil can be used as a heating fuel or can be further converted to advanced biofuels. Torrefaction (heating at 200-300 Â°C in the absence of oxygen, at atmopsheric pressure) converts biomass to bio-coal, which can be more easily used for power generation than untreated biomass.
The Advantages of Biofuels over Fossil Fuels. There are many advantages of biofuels over fossil fuels that make the alternative fuel source an attractive option now and in the future.Biofuels have been in production for the last few decades and have really begun to take off with the awareness of global warming going around the world. Biofuels do not release as much carbon as fossil fuels do, and because of this, there are fewer harmful emissions out of biofuels. 2  Renewable. 3  Being made from organic materials, and even organic waste, there is practically an infinite amount of biofuels available.
