Question

How are chemosynthetic bacteria useful for the ecosystem?

Answer 1

Hint: Chemoautotrophs, for example, are organisms that synthesise chemicals. Sulfur-oxidizing gammaproteobacteria, epsilon proteobacteria, and neutrophilic iron-oxidizing bacteria, as well as some archaea like methanogenic archaea, are among them.

Complete answer:
Chemosynthetic Bacteria are a type of autotrophic or photosynthetic bacteria that may manufacture their sustenance by oxidising various inorganic compounds. Chemosynthetic bacteria benefit the ecology by recycling nutrients such as nitrogen, phosphorus, iron, and sulphur.

Chemosynthetic bacteria get their energy through chemical processes and are found at the first trophic level, analogous to plants on the surface. In the absence of sunshine, they oxidise sulphides (or methane) and release energy from these molecules at deep sea hydrothermal vents.

Some of these bacteria dwell in the intestines of tubeworms and other bottom-of-the-food-chain species. Other (higher) species that prey on or scavenge these organisms gain access to the energy.

Chemosynthetic Bacteria's Importance: This makes them essential primary producers in a variety of settings where oxidants like nitrates and sulphates are present. In deep-sea vent habitats, for example, photosynthesis is impossible due to a lack of sunshine.


Bacteria are critical components of the global ecology. Their constant labour completes the cycling of nutrients like carbon, nitrogen, and sulphur. One of the most significant activities of bacteria is decomposition, which involves the breakdown of these organisms and the release of nutrients back into the environment.

Chemosynthetic autotrophs are creatures that can generate energy by oxidising inorganic compounds such as elemental sulphur, nitrates, and nitrites, among others. The energy generated during the oxidation process is used to produce ATP molecules. Chemoautotrophs is another name for them.

Note: Chemosynthesis is the biological conversion of one or more carbon-containing molecules (typically carbon dioxide or methane) and nutrients into organic matter utilising inorganic substances (e.g., hydrogen gas, hydrogen sulphide) or ferrous ions as a source of energy instead of sunlight.
