Question
If all the plants and trees vanish from the earth, the gas which will decrease is:
- 1 point
- Carbon dioxide
- Oxygen
- Water vapour
- Nitrogen
Solution
If all the plants and trees vanish from the earth, the gas which will decrease is Oxygen.
Here's why:
-
Plants and trees produce oxygen as a byproduct of photosynthesis. Photosynthesis is the process by which green plants, trees, and certain other organisms transform light energy into chemical energy.
-
During photosynthesis, plants absorb carbon dioxide (CO2) and sunlight to create fuel—glucose and other sugars—and oxygen (O2) is produced as a byproduct of this process.
-
If all the plants and trees were to vanish, there would be no photosynthesis, and therefore, no production of oxygen.
-
As a result, the amount of oxygen in the atmosphere would decrease.
So, the correct answer is Oxygen.
