      f) Every habitat has been recreated and contains most of the flora and fauna
         found in the original – dangerous and large animals have been left out. By in-
         stalling a carefully calculated balance of prey and predator, a complete food
         chain has been established.
      g) For example, the savanna grasses have to be broken down for recycling. This
         is done by termites, which, unfortunately, preferred the sealant around the
         panes of grass. The sealant had to be changed. Then there was the problem of
         how to seal the biosphere underground, and how to stop the air pressure
         blowing out the glass when it expanded in the sun’s heat. The former was
         solved by using plastic coated steel, the latter by, building a special pair of
         mechanical ‘lungs’ which expanded to accommodate the extra air volume.
      h) But it was the decisions of what to grow and what to eat which most greatly
         affect the eight scientists. They will grow wheat, sorghum, potatoes, peas and
         beans, and raise some miniature pigs. The ocean will also have a small stock
         of fish.

       9.4 Give the tittles to each paragraph

       9.5 Say what the different problems they had in designing the biosphere
           and how they were overcome

       9.6 Something to think about

        The American and Russian space programs were not only useful in terms of
space exploration, but there were also many spin offs – inventions which came to be
used in our everyday lives. Non-stick frying pans is an example. Can you think of any
findings from this experiment that might be useful to us in the same way?
