Read the following passage and use the information to answer the questions. Biomass fuel is the name given to renewable fuels obtained from living things. The most commonly used biomass fuel is wood. In many parts of the world, wood is the main fuel used for domestic heating and cooking. Charcoal and wood-alcohol are biomass fuels made from wood. Charcoal can be used in solid fuel heaters, while wood-alcohol is used as a liquid fuel. Charcoal is produced by heating wood in the absence of air. This process is called destructive distillation. The process also produces a mixture of gases which can be condensed to form an oily liquid. Wood-alcohol is obtained from this liquid. Sugar cane can be used to produce another liquid biomass fuel called ethanol. Sugar, which is extracted from sugar cane plants, is converted to ethanol by the process of fermentation. Ethanol can be burned to produce heat energy or used in a fuel cell to produce electrical energy.

Different types of lemur are found in Madagascar. Each type of lemur has a different colour of fur. The main diet of each lemur is different. The Bushbaby lemur has grey fur and feeds on insects. The Red-ruffed lemur eats fruit and has red, black and white fur. The Ring-tailed lemur and the Blue-eyed lemur both feed on fruit and leaves. The Ring-tailed lemur has grey, black and white fur but the fur of the Blue-eyed lemur is all black. Present this information as a table with three suitable headings.
