Give an example to prove that microbes release gases during metabolism?

The yeti crab is a crustacean that lives near extremely hot hydrothermal vents, where they wave their hairy forelimbs. Their limbs are covered in bacteria that convert methane (from the vent) to sugars. The crabs can often be seen waving their limbs in the water and clearing the bacteria off of their limbs with their mouthparts. Which statement below is true of this relationship? This is a commensal relationship. The crab benefits by gaining energy from the bacteria, and the bacteria neither gain fitness nor lose fitness. This is a parasitic relationship. The bacteria benefit at the expense of the crab that must waste energy keeping its limbs clean This is a mutualistic relationship. The bacteria have an ideal environment for growth and the crab has a primary source of carbohydrates in a nutrient-limited environment This is a commensal relationship. The bacteria have an ideal environment for growth and the crab has a primary source of carbohydrates in a nutrient-limited environment

Describe the evidence in support of or against the following statement: Humans consume microbes every day with little health risk.

You have discovered a cyanobacteria with only photosystem I. The bacteria is unable to fix CO2. Explain thoroughly how you think this microorganisms makes ATP and reducing power
