What is the ecological role of chemosynthetic autotrophic bacteria described in the chapter?

Chemosynthetic autotrophic bacteria oxidise inorganic substances such as nitrates, nitrites and ammonia and use the released energy for ATP production. Through these activities, they play an important role in recycling nutrients such as nitrogen, phosphorus, iron and sulphur.

Which type of bacteria play a great role in recycling nutrients like nitrogen, phosphorus, iron, and sulphur?

According to , chemosynthetic autotrophic bacteria are responsible for oxidizing inorganic substances such as nitrates and ammonia to produce ATP. Because they actively process and transform these elemental inorganic compounds, they play a fundamentally great and essential ecological role in recycling vital biosphere nutrients, including nitrogen, phosphorus, iron, and sulphur, maintaining biochemical cycles.
