1. Synthesis reaction refers to a chemical reaction when two or more units are supplemented together to produce a new compound.  

2. Chemical equilibrium refers to the condition when a reversible reaction is taking place in both the directions at a similar rate.  

3. Metabolism refers to all the chemical reactions that take place in the organism in order to maintain the processes of life.  

4. A reversible reaction refers to a chemical reaction in which the reactants used to produce the products can also be produced from those products.  

5. The product is produced as an outcome of a chemical reaction.  

6. Activation energy refers to the energy, which is needed to initiate a chemical reaction.  

7. An exchange reaction refers to a chemical reaction where the substrates trade constituent parts.  

8. Law of mass action refers to the situation where the concentration of reactant product affects the rate and net direction of a reversible chemical reaction.  

9. Decomposition refers to a chemical reaction where the compound is dissociated into its constituent parts.  

from my research i have to the conclusion that decomposers, such as fungi, bacteria and invertebrates, play a critical role in nutrient cycling and without them the earth's ecosystem may not support life as we know it. elements such as carbon, nitrogen and phosphorus exist in limited amounts on earth, although huge amounts of carbon are being released into the atmosphere from underground sources now by humans. it is still extremely important that other nutrients be retained by the process of re-use. decomposers are organisms that are able to chemically break down dead material and make these elements available for use by other organisms. without this breakdown of dead material, dead bodies would pile up. so decomposers also play a role in clean up also. without them, life might not continue as we know it and dead material would overwhelm the earth.
