Question:

Chemosynthetic autotrophic bacteria

Options:

1. Play a great role in recycling nutrients
2. Oxidises various organic substance
3. Release O₂ due to involvement of OEC
4. Are most abundant in nature

Solution:

Chemosynthetic autotrophic bacteria are involved in the cycling of nutrients such as nitrogen, sulfur, and iron in the ecosystem. They are also important in bioremediation, the process of using microorganisms to clean up pollutants in the environment. While they can oxidize various organic substances, this is not their primary role. They do not produce oxygen as a byproduct of their metabolism, as they do not contain an oxygen-evolving complex (OEC) like photosynthetic organisms. They are not necessarily the most abundant organisms in nature, as this can vary depending on the specific ecosystem.
