What is the Redfield Ratio, and how does it relate to algae and the idea of limiting nutrients? See the terms and concepts video attached to the Paper Discussion 2 assignment for a brief overview of the Redfield Ratio. What other nutrients, besides nitrogen and phosphorus, could potentially be limiting to phytoplankton? In 1961, Evelyn Hutchinson proposed the Paradox of the Plankton. Simply stated, he observed that there are a limited number nutrients for which to complete in seawater. By the principal of competitive exclusion, this should lead to a limited number of phytoplankton species. And yet, he observed, there are sometimes hundreds of species present in an area. Since, many solutions have been proposed to the paradox. Describe one of the proposed solutions.

It's dope how the answer addresses not just nitrogen and phosphorus as limiting nutrients but also brings up the idea of carbon being a potential limit for phytoplankton
