Question

What is chemosynthesis?

Answer 1

Chemosynthesis:

1. Chemosynthesis is the process in which bacteria make food with chemical energy.
2. In this process, one or more carbon molecules are converted into organic matter.
3. In this process, the chemical energy of compounds like carbon dioxide and hydrogen sulphide react to oxygen, producing the carbohydrates needed by the organism and other compounds as a byproduct.
4. The chemical equation for chemosynthesis involving hydrogen sulphide are:

$$\begin{gathered} 18{\mathrm{H}}_2\mathrm{S}+6{\mathrm{CO}}_2+3{\mathrm{O}}_2\to {\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6+12{\mathrm{H}}_2\mathrm{O}+18\mathrm{S} \\ \mathrm{Hydrogen}\mathrm{Carbon}\mathrm{Oxygen}\mathrm{Glucose}\mathrm{Water}\mathrm{Sulphur} \\ \mathrm{sulphide}\mathrm{dioxide} \end{gathered}$$
