Answer:
light energy, above the arrow
Explanation:
The photosynthesis process can be summarized in the following equation:
6 CO2 + 12 H2O + light energy → C6H12O6 + 6 O2 + 6 H2O.
As you can see, Navah's photosynthesis equation was missing the light energy above the arrow.
Although this equation is widely used to describe the process of photosynthesis, in reality, the first molecules to be formed are not glucose (C6H12O6), but simpler sugars with only three carbon atoms.
Photosynthesis is essential for life to exist on Earth the way we find it today, because it is through photosynthesis that oxygen on the planet is produced. In addition, photosynthesis is also responsible for producing energy for virtually all living things. Thus, photosynthesizing organisms underlie both terrestrial and aquatic food chains.
