   Aesthetic reasons for conserving biodiversity are less tangible but of great
   importance. We conserve species and habitats because they are beautiful or
   because they otherwise enrich our lives. The culture of a nation is closely
   allied to its landscapes and wildlife.

   Commensalism means literally 'at table together'. This is a symbiotic
   relationship between two species in which one species benefits and the other
   neither benefits or harms. Often, the host species provides a home and/or
   transportation for the other species.
   
   
   For example:
   
   
    i.) Epiphytes, e.g.some tropical orchids use trees or branches of trees for
   support without harm or benefit to the tree. The epiphyte obtains more light
   and air in this manner.
   
   
   ii.) Ecklonia maxima and Patella compressa. The Patella gets it food
   from the plant, the Euklonia, which is not harmed or damaged in the
   process.
