Do decomposition reactions require energy?
False. It requires heat - Lowering the temperature ie. refrigeration slows decomposition - freezing say in liquid nitrogen will virtually halt decomposition completely.

How are synthesis and decomposition reactions coupled in cells?
The synthesis and decomposition reactions are coupled in cells through the process of metabolism. There are chemical reactions that are used in this entire process.
Synthesis and decomposition reactions in an organism are called .?
All of the decomposition reactions in an organism taken together is called catabolism, while the synthesis reactions are called anabolism.
