Question

What process do some cyanobacteria perform, but other photosynthetic organisms cannot? [1 pt] glycolysis fermentation carbon fixation nitrogen fixation

Answer 1

Answer: Nitrogen fixation

Explanation:

Some cyanobacteria can fix nitrogen using a process in which atmospheric nitrogen is converted to ammonia, nitrites and nitrates. This will then be utilized by plants in synthesizing whichever substances they need.

Answer 2

Answer: Cyanobacteria perform nitrogen fixation.

Explanation:

Nitrogen fixation refers to a process where molecular nitrogen is converted to ammonia or nitrogenous compound in the soil for plant to absorb. Cyanobacteria are photosynthetic bacteria and are very important in nitrogen fixation. They convert atmospheric nitrogen into ammonia or nitrate. It is the fixed form that plant use for their growth and can obtain from the soil.
