Describe how the process of photosynthesis led to an increase in cellular respiration and more complex cells
koban [17]

Answer:

<u><em>BRIEF EXPLANATION</em></u>

Photosynthesis is the anabolic process of building up glucose and making O2 from CO2 and water while cellular respiration is the opposite catabolic process of breaking down glucose by oxidizing it with O2 to get CO2 and water.

Explanation:

<em><u>MAIN ANSWER TO THE QUESTION.</u></em>

Photosynthesis is like when you’re trying to gain muscle and you eat tuna and eggs to turn it into muscle tissue. This takes energy in the form of food just like how photosynthesis requires sunlight for energy.

Cellular respiration is like when impoverished people starve for a week because they don’t have sufficient food to eat for nutrients. They have to get them from somewhere else. So the body breaks down glycogen, body fat and muscle tissue to provide the energy.
