The level of carbon dioxide was measured in a garden and on a city road. Where do you think the carbon dioxide level will be hig
her and why? A. The carbon dioxide level will be same at both places because the amount of carbon dioxide at all places on the earth is the same.
B. The carbon dioxide level in the city will be higher because the exhaust gases from vehicles release carbon dioxide and there are not many trees to utilize it.
C. The carbon dioxide level in the garden will be higher because of the many plants present which are constantly releasing carbon dioxide by photosynthesis.
The answer is <span>B. The carbon dioxide level in the city will be higher because the exhaust gases from vehicles release carbon dioxide and there are not many trees to utilize it.
It is known that in photosynthesis, plants use carbon dioxide and convert it into organic compounds. So, in a garden, there will be a lower amount of carbon dioxide than in a city. In the city, vehicles will release it in the atmosphere and if there are not many trees to utilize it, the carbon dioxide level in the city will be higher than in the garden.</span>
