where are areas in the world in which there is a strong connection between photosynthesis and cellular respiration? Explain why
guajiro [1.7K]

Answer:

The strong connection between photosynthesis and cellular respiration can be found everywhere in the Earth. This is because the reactants of the cellular respiration are the products of photosynthesis and vice versa.

The equation of photosynthesis can be summed up as:

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Carbon dioxide + water + energy from light → glucose and oxygen

The equation for cellular respiration can be summed up as

C6H12O6 + 6O2 → 6 CO2 + 6H2O + ATP

glucose +oxygen → Carbon dioxide + water + energy

As the equation shows, both the reactions are opposite to each other and hence hold a strong connection.
