Source sentences:
text: Iron is often a limiting factor for water organisms in surface layers.
text: Iron is essential for nitrogen binding and nitrate reduction, and it may be a limiting factor for phytoplankton growth.
text: It is highly insoluble in sea water and in a variety of locations is the limiting nutrient for phytoplankton growth.
text: Due to the high reactivity of Fe2+ with oxygen and low solubility of Fe3+, iron is a limiting nutrient in most regions of the world.
text: The Iron is the most common limiting element that have a key role in structuring phytoplankton communities and determining its abundance, it's particularly important in the HNLC (High-nutrient, low-chlorophyll regions), where the presence of micronutrients is mandatory for the total primary production, and Iron is considered one of those limiting factors.
