Photosynthesis is the process by which plants, and some other organisms, produce their own energy source, making them autotrophs or producers rather than heterotrophs or consumers, which gather energy by consuming other animals. Photosynthesis does not occur at a constant rate regardless of external conditions, rather, its rate is dependent on several external conditions. If it stays in the normal air, it remains red. Why does the pH indicator go from pink to clear when someone exhales through a straw into the solution?
