C: primary Consumer
<em>primary consumers</em> are typically animals that eat plants aka herbivores. 
<em>producers </em>would be plants
<em>secondary consumers </em>are typically ones that eat meat or eat meat and plants aka omnivores.
 <em>decomposers, </em>I believe are like your fungus or anything that feeds off of dead organisms or eat the waste of that organism.
Hopefully this helped. I  remember learning about this in college.  
 
        
             
        
        
        
 <span>DNA contains the code for all an organism's protein. Since many of the organism's structures, processes, and growth depend on protein the DNA is central to the well being of all organisms. In eukaryotes, the DNA is locked up in the nucleus. The area of the cell where proteins are made is in the cytosol (ribosomes). In order for the protein to be made the DNA has to produce a copy of the blueprint m-RNA. This messenger RNA will take the code to the ribosome. The process by which m-RNA is made is called transcription. A-U, C-G base pairing rules. Once on the ribosome another RNA comes into play t-RNA. This is called transfer RNA. Here it will take an amino acid and place it in the correct order to produce the desired protein. This is called translation. It begins with a start co don AUG. and ends with a stop codon. The protein will then go to the Golgi apparatus and be formed into its final shape.
