Question

In a glasshouse, how could carbon dioxide concentration be increased?

A) By increasing the temperature in the glasshouse.
B) By decreasing the humidity inside the glasshouse.
C) By adding more oxygen to the atmosphere.
D) By releasing carbon monoxide into the glasshouse.

Answer 1

To increase carbon dioxide concentration in a glasshouse, external sources of CO₂ need to be introduced, as the options listed in the question would not directly increase CO₂ levels. CO₂ generators or compressed CO₂ are typically used in such situations.

Step-by-step explanation:

Increasing Carbon Dioxide Concentration in a Glasshouse

To increase the carbon dioxide concentration in a glasshouse, none of the options provided in the question would be directly effective. Instead, growers often use carbon dioxide generators or introduce compressed CO2 to increase the concentration within the glasshouse. Understanding the relationship between carbon dioxide and photosynthesis is crucial since plants use CO2 during this process to generate food and release oxygen. Therefore, an augmented level of CO2 can improve plant growth and yields, especially in a controlled environment like a glasshouse. Meanwhile, the increase in global atmospheric CO2 from pre-industrial levels due to human activities has raised concerns about global warming and climate change, demonstrating a different context where CO2 levels impact the environment.
