Which of the following clearly shows the importance of carbondioxide i...
The correct answer is option A: 1 and 4 only.
Explanation:
1. It is essential for the growth of plants:
Carbon dioxide plays a crucial role in photosynthesis, the process by which plants convert sunlight into energy. During photosynthesis, plants absorb carbon dioxide from the atmosphere and use it, along with water and sunlight, to produce oxygen and glucose. Glucose is the primary source of energy for plants, and it is also used to build other essential molecules such as cellulose. Without carbon dioxide, plants would not be able to grow and survive, and the entire ecosystem would be greatly affected.
4. Ocean absorbs carbon dioxide from the atmosphere to form carbonate rocks:
The oceans act as a carbon sink, absorbing large amounts of carbon dioxide from the atmosphere. This absorbed carbon dioxide reacts with water to form carbonic acid, which then reacts with calcium carbonate present in the water to form carbonate rocks such as limestone. This process, known as carbon sequestration, helps to regulate the levels of carbon dioxide in the atmosphere. It also plays a significant role in the carbon cycle, as carbon gets stored in these rocks for millions of years, thus reducing the amount of carbon dioxide in the atmosphere.
2. It is the most abundant gas in the atmosphere after nitrogen and oxygen:
While carbon dioxide is not the most abundant gas in the Earth's atmosphere, it still plays a significant role. Nitrogen makes up about 78% and oxygen about 21% of the atmosphere, while carbon dioxide constitutes just a small fraction, around 0.04%. However, even in small amounts, carbon dioxide has a powerful impact on the Earth's climate due to its greenhouse effect. It traps heat in the atmosphere, preventing it from escaping back into space and thus leading to global warming.
3. It absorbs the heat directly incoming from the Sun, thus warming the planet:
This statement is incorrect. Carbon dioxide does not directly absorb heat from the Sun. Instead, it acts as a greenhouse gas, trapping heat that is radiated from the Earth's surface. This phenomenon is known as the greenhouse effect and is essential for maintaining the Earth's temperature within a habitable range. However, excessive amounts of carbon dioxide in the atmosphere can lead to an enhanced greenhouse effect, resulting in global warming and climate change.
Therefore, the correct options that clearly show the importance of carbon dioxide in the Earth's atmosphere are 1 and 4 only (option A).
