Question

Maya wrote a few steps to describe how carbon circulates between the atmosphere and living organisms. Step 4 is missing.

Step 1: Carbon enters the atmosphere as carbon dioxide from respiration and combustion
Step 2: Plants use carbon dioxide to make glucose
Step 3: Plant-eating animals consume the glucose present in plants
Step 4:
Which of the following best describes step 4?

Answer 1

The glucose is broken down in the blood to release CO2 ,which returned to the atmosphere through the process of respiration !

Step-by-step explanation:

• When the animal eats the plant , the glucose is absorbed in the blood stream through the intestine.
• The glucose enter the cell,through the cytoplasm into the mitrochondria
• Mitrochondria is called the power house of the cell , it generates the energy through break down of glucose
• The process of breaking the glucose into energy is a cycle called the glycolysis .
• At the end of this process CO2 is by product ,that is taken by circulating blood to the lungs
• From there through the alveoli the gases are exchange due to difference in the partial pressure and CO2 is expelled out and oxygen enters blood stream and the cycle continues .
