Trichodesmium is a nitrogen-fixing cyanobacteria. why might this cyanobacteria be important to other organisms in nitrogen-poor waters?
they convert atmospheric nitrogen (n2) to organic compounds including ammonia (nh3).
they convert inorganic nitrogen to ammonia (nh3) in the ocean.
they convert organic nitrogen compounds to into other nitrogen compounds. they convert nitrates from the water into nitrogen gas (n2) that is released into the atmosphere.

They convert atmospheric nitrogen (N₂) to organic compounds including ammonia (NH₃).

Trichodesmium is cyanobacteria which converts atmospheric nitrogen into ammonia which is then used by other organisms present in the nitrogen poor water. They are found in the nutrient poor tropical and sub tropical ocean waters .They account for approximately half of the nitrogen fixation in marine system all over the world.

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics

i think it’s c but i might be wrong. if i am let me know! have a good rest of your day as well!
