Tropical rainforests are rich
        
        
          habitats for a huge variety of
        
        
          plants and animals. Enter a hot,
        
        
          damp, and shady world.

          A rainforest is warm and sticky, with
        
        
          frequent downpours. The trees take up
        
        
          much of the rain, but water vapour
        
        
          soon evaporates from their leaves,
        
        
          filling the air with moisture.
