Which nutrients often limit the distribution and abundance of photosynthetic organisms?

Photosynthetic organism growth is limited by nutrients which are the nitrogen and phosphorus. Too much nutrients affect the growth of algae. Too many algae can cause an algae bloom. An alga does not live long and can die immediately which causes decomposition that gets too much oxygen in the waters. When oxygen decreases in the water living organisms in it will be affected.

Well, both latitude and intensity of light affect temperature because, the higher the light intensity, the higher the temperature and since latitude is the measure of how close you are to the equator, then the closer to the equator you are, the higher the temperature is.
