Explanation:

Plants need sufficient light for photosynthesis, carbon dioxide as a core reactant for photosynthesis, and nutrients for growth and development. In a closed greenhouse, these resources can be depleted faster than they are replenished, even if water and temperature are controlled. Identifying this limiting factor allows the farmer to adjust conditions (e.g., add CO₂ supplements, install grow lights, or fertilize) to maximize plant growth and yield.

Answer:

The limiting factor would typically be one of the key resources required for plant growth that is in shortest supply in the greenhouse, such as carbon dioxide concentration, light intensity, or nutrient availability (e.g., nitrogen, phosphorus).
