The principle that photosynthesis is limited by the factor in shortest supply is:

Answer: Blackman's law of limiting factors.

  • A The Van't Hoff temperature rule
  • B Blackman's law of limiting factors
  • C Mendel's law of segregation
  • D The Hardy-Weinberg equilibrium

Correct answer: B. Blackman's law of limiting factors

Explanation: Blackman's law of limiting factors states that the rate is set by the resource (light, CO<sub>2</sub>, temperature) that is most in short supply.

Photosynthesis: Inputs and OutputschloroplastLeaf cellSunlightCO2H2OO2Glucose

Simplified photosynthesis diagram: light energy, CO2, and H2O enter the leaf and are converted in the chloroplast into glucose and O2.

Concept context

Light reactions, the Calvin cycle, C 3 /C 4 /CAM pathways, photorespiration, and factors affecting the rate of photosynthesis. One of the highest-yield NEET chapters.
