Question

Greenhouse gas, which can be emitted from storage of nitrogen based fertilizers, is:
A. Nitrous oxide
B. Nitric oxide
C. Oxygen
D. Hydroxide

Answer 1

Greenhouse gas is a gas which absorbs and emits radiant energy from the sun within the thermal infrared range. Greenhouse gases cause the greenhouse house effect on the planet. Greenhouse gases include water vapour, carbon dioxide, methane, nitrous oxide and ozone.

Complete step by step answer:
The three most important agricultural greenhouse gases are carbon dioxide, methane, and nitrous oxide. Nitrous oxide is several times more potent than carbon dioxide and is a very important greenhouse gas emitted from field crops. For example, 61% of greenhouse gas emissions from corn production are from nitrous oxide and production of nitrogen based fertilizer. Most nitrogen based fertilizers contain nitrates which decompose slowly, in the presence of oxygen, to give harmful greenhouse gas like nitrous oxide. Nitrous oxide is a gas produced naturally by soil microbes. Much more nitrous oxide is produced when there is abundant nitrogen in the soil.
Here, we have clear that the greenhouse gas that is derived from nitrogen based fertilizers is nitrous oxide.

So, the correct answer is Option A.

Additional Information:
Atmospheric levels of carbon dioxide—the most dangerous and prevalent greenhouse gas—are at the highest levels ever recorded. Greenhouse gas levels are so high primarily because humans have released them into the air by burning fossil fuels.

Note: The greenhouse effect is a natural process that warms the earth’s surface. When the Sun’s energy reaches the Earth’s atmosphere, some of it is reflected back to space and the rest is absorbed and re-radiated by greenhouse gases. When the amount of greenhouse gases are increased the re-radiated energy also increased as it causes the temperature of earth’s atmosphere and leads to global warming
