Question
In your experiments, under default conditions, the cyanobacteria population initially grew faster than the green algae population, but cyanobacteria were ultimately outcompeted by green algae. Assuming that phosphorus is required for reproduction, which of the tradeoffs below did this outcome reflect?
a.Cyanobacteria are more efficient at taking up nutrients when phosphorus concentrations are low, but less efficient when phosphorus concentrations are high.
b.Green algae are more efficient at taking up nutrients when phosphorus concentrations are low, but less efficient when phosphorus concentrations are high.
c.Cyanobacteria are efficient at taking up nutrients when phosphorus concentrations are low, but they have a high R*.
d.Green algae are efficient at taking up nutrients when phosphorus concentrations are low, but they have a high R*.
Explanation / Answer
Generally with increase in concentration of phoshates, reproduction of green algae increases.
According to avalaible options, option c) is correct
When concentration is low, cyanobacteria growth rate is faster than the green algae and when the concentration increases the growth rate of green algae increases so rapidly that it left cyanobacteria uncompetitive.
