  3. Weeding

  4. None of the above

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Weeding is the process of removing unwanted plants in a crop. Once weedicides are applied, they contain harmful elements like DDT and many more which can leach into the soil and cause soil pollution and cause death of beneficial micro fauna present in the soil. These weedicides can also reach to the aquatic bodies by runoff water, causing algal blooms and thereby leading to the death of aquatic fauna.

Many marine animals use carbonates dissolved in sea-water to make their shells. Which of the following component is reduced in our atmosphere by this biological phenomenon?

  1. Oxygen

  2. Calcium carbonate

  3. Carbon dioxide

  4. Nitrogen

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Shell of many marine organism are made of calcium carbonate. Carbonate is formed when carbon dioxide (CO2) from atmosphere get react with the sea water. It also help us to maintain carbon dioxide level in the atmosphere because today scenario is very alarming due to increasing level of carbon dioxide. 

So, the correct option is 'Carbon dioxide'.
