    Acid rain has been linked to an increase in (1. sulphur dioxide) in the atmosphere. This increase is mainly due to the burning of (2. fossil)(3. fuels)such as (4. coal).

    One way of reducing the problem may be to use biogas produced by microorganisms kept in warm (5. anaerobic) conditions. These microorganisms convert (6. organic waste) into this renewable energy source.

    I think you extracted this exercise from [http://www.colchsfc.ac.uk/biology/newsite/newcloze... with the topic [Pollution and Renewable Fuels], am I right?

    Anyway, I have checked all the answers online, they are all correct. You may go to the same website and type my answers to check again.
