Question
______________ dissolved in water helps in the photosynthesis of aquatic plants.
- Oxygen
- Sulfur
- Carbon dioxide
- Nitrogen
Hint:
Aquatic plants remain submerged in water and therefore do not have an excess of the gases that are abundantly available in the atmosphere. Therefore aquatic plants utilize the essential gases dissolved in water to carry out their biological processes.
The correct answer is: Carbon dioxide
Carbon dioxide dissolved in water helps in the photosynthesis of aquatic plants.
Aquatic plants intake the carbon dioxide dissolved in water and in the presence of sunshine prepare their food through the process of photosynthesis. The purpose of this biochemical process is to utilize carbon dioxide as a carbon source and prepare glucose which is the simplest form of carbohydrates available.
