          Fungi (like toadstools,
        
        
          mushrooms, and moulds)
        
        
          are neither plants nor
        
        
          animals, but they’re more
        
        
          like plants than animals.

          Insects such as
        
        
          butterflies are
        
        
          invertebrates.
        
        
          
            Animals
          
        
        
          The animal kingdom is
        
        
          made up of vertebrates
        
        
          (animals with a backbone)
        
        
          and invertebrates (animals
        
        
          without a backbone).
        
        
          
            The living world

            Micro-organisms
          
        
        
          Micro-organisms are very
        
        
          tiny – they are made up
        
        
          of a single cell.

          Plants cannot move
        
        
          around like animals. To
        
        
          survive and grow, they
        
        
          have to make their own
        
        
          food. In turn, plants
        
        
          provide food for many
        
        
          animals and fungi.

          Living things share some
        
        
          characteristics. They all
        
        
          need food and oxygen. They
        
        
          also grow, reproduce, and
        
        
          adapt to their environment.
