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.

a researcher conducts an experiment on the secretion of a particular hormone in mice. scientists inject mice with a substance that stimulates the production of the hormone. the scientists then test the levels of hormones produced by the mice. the tool used to measure the hormones consistently detects the levels at 10 points lower than the actual hormone levels in the mice. this tool makes measurements, but the measurements aren't .
