    What are essential nutrients for bacteria?

    Include C, H, O, N, P, K, S, and Fe.

    How do autotrophs obtain carbon?

    Convert CO₂ into organic compounds.

    What is the role of nitrogenase in bacteria?

    Enables fixation of atmospheric nitrogen.

    What are macronutrients?

    Major elements required in larger quantities.

    What distinguishes phototrophs from chemotrophs?

    Phototrophs use light; chemotrophs use chemical reactions.

    What are micronutrients?

    Trace elements needed in minute quantities.

    What is the function of sulfur in bacteria?

    Component of amino acids and some vitamins.

    What do photoautotrophs use for energy?

    Light as an energy source and CO₂ as carbon.

    What is the difference between photoheterotrophs and chemoheterotrophs?

    Photoheterotrophs use light; chemoheterotrophs use organic compounds.

    What are growth factors in bacteria?

    Essential nutrients required in very small amounts.

    What is the primary carbon source for heterotrophs?

    Organic compounds from other organisms.

    What happens during photosynthesis in cyanobacteria?

    Oxygen is produced by reducing CO₂.

    What is the significance of thylakoids in bacteria?

    Site of photosynthesis in phototrophic bacteria.

    What are organotrophs?

    Bacteria that use organic compounds as electron donors.

    What is the role of phosphorus in bacterial cells?

    Component of nucleic acids and ATP.

    What do lithotrophs use as electron donors?

    Reduced inorganic compounds.
