Question description

  1. Look at the illustration of a trophic level pyramid. For each trophic level, write one or two sentences explaining the role of that type of organism. You should include those organisms that fall outside the normal pyramid. Give an example of each type of organism.Your examples do not have to belong to the same food chain in real life. Why does the pyramid get narrower at each higher level?

2.  What is an environmental sphere or earth system sphere? Name the earth’s five major environmental spheres and state the defining characteristics of each. Give one example of a way in which two or more earth system spheres interact.
