Question
To sustainably feed a growing population, we will need to produce more food per unit of land. This means increasing crop yields. Which of the following factors is/are the biggest restriction(s) to crop yields? Select all that apply.Light availabilityLevel of CO₂TemperatureWater availability123456789
Solution
All of the factors listed can potentially restrict crop yields:
-
Light Availability: Light is essential for photosynthesis, the process by which plants convert sunlight into chemical energy. Without sufficient light, plants cannot produce the energy they need to grow.
-
Level of CO₂: Carbon dioxide is another key ingredient in photosynthesis. If CO₂ levels are too low, it can limit a plant's ability to produce energy.
-
Temperature: Plants have optimal temperature ranges for growth. If temperatures are too high or too low, it can stress the plant and reduce yield.
-
Water Availability: Water is crucial for plant growth. It is involved in all aspects of plant metabolism. Lack of water can lead to wilting and, in severe cases, death of the plant.
So, all of these factors - light availability, level of CO₂, temperature, and water availability - can be the biggest restrictions to crop yields.
