How does limited Carbon Dioxide affect plant growth in a greenhouse?

Limited carbon dioxide in a greenhouse significantly impacts plant growth because carbon dioxide is a crucial ingredient for photosynthesis. In this process, plants convert carbon dioxide and sunlight into glucose, which serves as food for their growth. When carbon dioxide levels are insufficient, the rate of photosynthesis is hindered, meaning that plants cannot produce adequate energy and biomass necessary for healthy development. As a result, growth is stunted, leading to smaller plants and reduced yields. This principle underscores the importance of maintaining optimal levels of carbon dioxide in controlled environments such as greenhouses to promote healthy plant growth.
