A limiting factor is a variable of a system that causes a noticeable change in output or another measure of a type of system. The limiting factor is in a pyramid shape of organisms going up from the producers to consumers and so on
Explanation:
1.Observe: SetTemperatureto 24°C,Light intensityto 50%, andCO2levelto 200 ppm.A.Move theTemperatureslider up and down. Were you able to increase oxygenproduction?a.No, I was not able to because oxygen production cannot increase more than24C.(Return the slider to 24°C when finished.)B.Move theLight intensityslider back and forth. Were you able to increase oxygenproduction?a.No, I was not able to increase oxygen production because it remained thesame from 27% to 100%.C.Move theCO2levelslider back and forth. Were you able to increase oxygenproduction?a.Yes, I was able to increase oxygen production because with a higher CO2level the production increased.(Return the slider to 200 ppm when finished.)2.Analyze: In this situation, what was the limiting factor? How do you know?a.The limiting factor was CO2 because when it was decreased or increased, itincreased oxygen production.3.Challenge: In each of the situations below, use the Gizmo to find the limiting factor.TemperatureLight intensityCO2levelLimiting factor25°C60%700 ppmLight intensity
