C4 plants are more productive. Why?

1.	C4 plants are more productive. Why?
Answer» 1. Photorespiration is considered to be a wasteful process in plants. It is an energy consuming process in plants which ultimately leads to reduction in final yield of plants. 2. During C₃ photosynthesis, 25% of the carbon dioxide fixed has to pass through photorespiratory process. 3. This decreases the photosynthetic productivity. 4. In C₄ plants, photorespiration is absent and hence they have better productivity.
