Based on the diagram shown above and what you
know about food webs, which of the following
conclusions is correct?

   web can survive.
2. Since organisms within a food web are
   interdependent, the disappearance of one organism
   within the food web could affect all the
   organisms within that web.

   food web, the energy available within the food
   web remains constant.

   for food, the disappearance of one organism
   within the food web helps other organisms within
   the web to survive.
