Answer 1

Answer:

b option is correct

Explanation:

when we put some seeds of beans or anything the seed will use oxygen for the respiration so when we introduce a burning candle in the vessel then it will stop burning because the seeds have used the oxygen for their respiration there is only carbon dioxide in the vessel and as you know that combustion requires oxygen but in the vessel there is no oxygen so the candle will stop burning

Answer 2

Oxygen consumption during seed germination is the correct answer.

• Seeds require oxygen for germination along with the right temperature and right amount of water. It is impossible for the seeds to germinate without oxygen.
• Hence when the seeds were germinating, they consumed all the oxygen present in the dark vessel which was covered with a cork.
• And when a burning candle was introduced, it stopped burning because there was no oxygen left for the candle to burn.
