Answer: Li_2CO_3\rightarrow Li_2O+CO_2

Explanation:

Decomposition is a type of chemical reaction in which one reactant gives two or more than two products.

A\rightarrow B+C

1. Li_2CO_3\rightarrow Li_2O+CO_2 is an example of decomposition.

2. Zn+HCl\rightarrow ZnCl_2+H_2 is an example of single replacement reaction in which more reactive element displaces the less reactive element from its salt solution.

3. Na_2O+CO_2\rightarrow Na_2CO_3 is an example of synthesis reaction in which two reactants are combining to form one product.

4. C_6H_{12}O_6+O_2 \rightarrow CO_2+H_2O is an example of combustion in which fuel is reacted with oxygen to form carbon dioxide and water.

Answer: catabolism

Explanation:

Catabolism refers to the set of metabolic pathways which is necessary for the breaking down of molecules into smaller units. This is then oxidized for the release of energy or can be used to perform other anabolic reactions.

Catabolism is regarded as the opposite direction of anabolism which is simply the building-up of molecules. It should be noted that anabolism and catabolism work together in every living organisms and perform functions such as the production of energy and the repair of cells.
