Question

Two friends while travelling slept under the tree at night. Early morning, one of them felt dizzy State reason for her condition.​

Answer 1

Answer:

During the night, plants respire. Since during respiration carbon-di-oxide is released, the air had more concentration of carbon-di-oxide than oxygen. The lack of oxygen in her body, made one of them feel dizzy.

Answer 2

I hope you understood

Explanation:

When we respire we produce Carbon Dioxide and Energy. Just like that palnts alo produce Carbon Dioxide whn they respire. Now you might be thinking how it is possible because plants produce oxygen? In the day, plants produce Oxygen with energy. But in the night, plants produce Carbon Dioxide as a result of Aerobic Respiration.

So if a person sleeps under a tree at night, they will take in carbon dioxide because the tree produces carbon dioxide at night.
