The Food Chain..

One thing they teach in school biology is the concept of food chains and food webs – the links that show interdependence of organisms based on the foods they eat. The photo below shows one such food chain starting with the rose (the producer) providing nourishment in the form of sap for aphids. In turn aphids are milked by ants for honeydew, a secretion that aphids produce.  Ants are also known to “farm” aphids storing their eggs over winter and then carrying newly hatched aphids to emerging plant shoots in spring (called a mutualistic relationship).

A mini food chain. In this picture clusters of aphids can be seen underneath petals of the rose, and ants that farm these aphids. Click on the photo for a larger version on Flickr.
