After millions of years, the remains of living things will turn into fossil fuels which are natural fuels. The combustion of these fossil fuels is important for the running of machinery, raising temperature in reactions and many more.
This is what is commonly know as 'peat'. Peat is found in peatlands, bogs, mires and moors, and is an accumulation of partially decayed vegetation or organic matter. The decay is slowed down by a lack of oxygen due to waterlogged conditions. These areas are very important carbon sinks as the CO2 released by the decaying matter is trapped within the peat. It requires thousands of years for peatland to develop. Peatlands are very important as they provide a record of past vegetation and climate within the preserved plant remains.
An undifferentiated cell of a multicellular organism which is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation.
