- A Growth is sometimes thought to be limited specifically by whichever nutrient is present in the greatest abundance overall
- B The scarcest essential nutrient relative to its requirement limits organism growth (limiting factor)
- C All essential nutrients are sometimes thought to contribute roughly equally to limiting an organism's growth rate
- D Organism growth is sometimes thought to be limited mainly by the single nutrient present in maximum supply available
Correct answer: B. The scarcest essential nutrient relative to its requirement limits organism growth (limiting factor)
Explanation: Liebig law of the minimum: growth rate of an organism is determined by the one essential nutrient (or factor) that is in shortest supply relative to the requirement, regardless of others.
