Limiting Factor
An abiotic or biotic factor that prevents an organism or population from increasing beyond a certain level.
Real World
In sub-Saharan Africa, water availability — not temperature or soil nutrients — is the main limiting factor for crop yields, which is why irrigation projects in Kenya's Tana River region dramatically increased food production.
Exam Focus
Link limiting factors to Liebig's Law of the Minimum by name; examiners reward correct use of named principles.
