Interactions of Limiting Factors (OCR GCSE Biology A (Gateway Science Suite)): Flashcards

An environmental condition that restricts photosynthesis rate when in short supply

Light intensity, carbon dioxide concentration, temperature

Line levels off/flattens

Rate increases until another factor becomes limiting

Increase light intensity, CO₂ levels, maintain optimal temp

Faster plant growth, higher yields, increased profits

$\frac{1}{\text{Distance}^2}$

Falls to a quarter of its original value

$\text{Light Intensity} \propto \frac{1}{\text{Distance}^2}$

$\frac{1}{4}$ of original ($\frac{1}{2^2} = \frac{1}{4}$)
