Solution

If all the plants and trees vanish from the earth, the gas which will decrease is Oxygen.

Here's why:

  1. 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.

  2. 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.

  3. If all the plants and trees were to vanish, there would be no photosynthesis, and therefore, no production of oxygen.

  4. As a result, the amount of oxygen in the atmosphere would decrease.

So, the correct answer is Oxygen.
