1. The difference between economicvalues or impacts and ecological roles
   • Ecology = roles in the ecosystem = list of everything I could think of and examples downloadable inLearning Module: Chapter 25
   • Economic = the economy = making and spending $money$

• • • EXAMPLE: I ask about economic values or impacts of protists and you tell me about brown algae playing a role as a primary producer, providing oxygen to as well as a habitat - for example the kelp forests off the coast of California or the "seaweed" (usually Sargassum, actually) that washes up on the beaches in Galveston and has little crustaceans living in it. Those are ECOLOGICAL ROLES; I asked for ECONOMIC ($$$) values or impacts.
