In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) an
gregori [183]

The question is incomplete, the complete question is;

In the process of photosynthesis, plants use carbon dioxide (CO2), water (H2O), and light energy to produce a sugar (C6H12O6) and oxygen (O2). In the process of aerobic cellular respiration, animals and plants release energy from sugar and oxygen and produce carbon dioxide and water. The chemical equations that describe these reactions look like this:

photosynthesis: 6CO2 + 6H2O + light ---> C6H12O6 + 6O2

cellular respiration: C6H12O6 + 6O2 ----> 6CO2 + 6H2O + 36 ATP

How do these equations explain why the total amount of O2 and CO2 remains the same?

Answer:

See explanation

Explanation:

If we look at photosynthesis and cellular respiration, we will realize that the both are complementary processes. The product of one process is the input material for the other process.

Respiration and cellular respiration helps to balance the amount of O2 and CO2 in nature because photosynthesis takes in CO2 and releases oxygen while cellular respiration takes in oxygen and releases CO2. This maintains the delicate balance between the both gases in nature.

Why was the Euglena green in color? What is the name of the specialized body structure that is located at the base of the tail?
sweet [91]
The Euglena was green because it had chloroplasts in it, just like plants. The body structure at the base of the tail that relates to this is the photo receptor. These two enabled it to photosynthesize food like plants, but it could also take food from its surroundings like animals.
