Interactions of Limiting Factors (AQA GCSE Biology Combined Science): Flashcards

Environmental condition restricting rate when in short supply

Light intensity, CO₂ concentration, temperature

Initially increases, then levels off when another factor limits

Light intensity, CO₂ levels, optimal temperatures

Faster growth, higher yields, increased profits

Inversely proportional to square of distance from source

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

Falls to 1/4 (a quarter) of original value

1/4 of original: $\frac{1}{2^2} = \frac{1}{4}$

Ensure plants receive adequate light for optimal photosynthesis
