Activity 1. Researching Everglades Food WebsEach organism has a role in an ecosystem. Producers transform energy from the sun into sugars that they can use to build their bodies or store to use later. Consumers can’t make their own energy. They eat producers or other consumers to get their energy. Decomposers break down dead organisms and waste materials and return nutrients to the ecosystem.1. What are some producers, consumers, and decomposers that live in the Florida Everglades? Use the Internet or library to make a list of the organisms that are found there. For the consumers, also make a note of what each consumer eats.

The scheme below is from a series of reactions that are part of a synthesis of vitamin a. answer the following questions with reference to this scheme. (i) what is "reagent a"? (ii) draw a step-by-step mechanism which explains the formation of compound c from compound b (iii) which reagents would you use to form compound e from compounds c and d (reagents b and c)? for each reagent suggested above in (ii) explain the role of the reagent in the reaction to (iv) form compound e. you may wish to do this by drawing a mechanism. 1. addition of reagent a но reagent a 2. н,о" thо oh нон-с compound a. compound b. compound c .ch-оh 1. reagent b "сно 2. reagent c сh oh compound e. compound d.
