chemosynthesis Definition
the biological conversion of one or more carbon molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g. hydrogen gas, hydrogen sulfide) or methane as a source of energy, rather than sunlight, as in photosynthesis.
Using chemosynthesis: Examples
Take a moment to familiarize yourself with how "chemosynthesis" can be used in various situations through the following examples!
Example
Chemosynthesis is the process by which certain bacteria synthesize organic compounds from inorganic compounds, such as hydrogen sulfide.
Example
Chemosynthesis is used by microbes living in extreme environments, such as deep sea hydrothermal vents.
Example
Chemosynthesis is an important process in the nitrogen cycle, converting ammonia to nitrite and nitrate.
Summary: chemosynthesis in Brief
The term 'chemosynthesis' [ˌkiːməʊˈsɪnθəsɪs] refers to the biological conversion of carbon molecules and nutrients into organic matter using the oxidation of inorganic compounds as a source of energy, rather than sunlight. This process is used by certain bacteria living in extreme environments, such as deep sea hydrothermal vents, and is important in the nitrogen cycle.
