Document Summary
Nostacales are kind of cyanobacteria that are capable of producing heterocysts, and it is the site of nitrogen fixation. Rank the temperature optima of the following phytoplankton groups: green algae, cyanobacteria, diatoms. Cyanobacteria have the highest tempoerature tolerance (greater than 45 degrees celcius), green algae, diatoms. What is the connection between paradox of the plankton and vonbig"s law of minimum vs. Von liebigs law of the minimum support the production (growth) is limited by the resource in the shortest supply; difference species have different resource requirements. The paradox states that all plankton have essentially the same ecological resource requirements. The hypothesis was rejected based on the fact that # of phytoplankton species is not related to the size and area of lake which he argued should be correlated to the number of microhabitats. Vonliebig"s law of the minimum states that production is limited by the resource in the shortest supply; different species have different resource requirements.
