How is the majority of carbon transferred from plants and animals to the soil?
1. The decay of dead organisms releases some carbon atoms from their bodies into the soil.
2. Carbon atoms from plant and animal waste dissolves into the soil.
3. Carbon dioxide from plant and animal respiration dissolves into the soil.
4. The decay of dead organisms releases carbon dioxide from their bodies into the soil.
All of the above statements are accurate and collectively contribute to the transfer of carbon from plants and animals to the soil. The majority of carbon transfer occurs through the decay of dead organisms, as their organic matter breaks down and releases carbon atoms into the soil. Additionally, carbon atoms from plant and animal waste, such as fallen leaves or animal droppings, dissolve into the soil. Carbon dioxide, produced during plant and animal respiration, can also dissolve into the soil.
Which of the 4 is correct
All four statements are correct.
it is one answer
The majority of carbon is transferred from plants and animals to the soil through the decay of dead organisms, which releases some carbon atoms from their bodies into the soil. Therefore, the correct answer is option 1: The decay of dead organisms releases some carbon atoms from their bodies into the soil.
Is all of Earth's carbon dioxide supply constantly being used by organisms?
1. Yes, and it briefly passes through the atmosphere as it cycles between organisms.
2. Yes, and it is used up as soon as it is formed.
3. No, some is stored in Earth's carbon sinks, such as the oceans.
4. No, some is stored in Earth's only carbon sink, the atmosphere
The correct answer is:
3. No, some is stored in Earth's carbon sinks, such as the oceans.
While organisms do utilize carbon dioxide for various processes, not all of Earth's carbon dioxide supply is constantly being used by organisms. Some carbon dioxide is stored in Earth's carbon sinks, such as the oceans. These carbon sinks serve as long-term storage for carbon dioxide, helping to regulate the carbon cycle and maintain balance in the Earth's atmosphere.
Which of these is the largest living carbon sink?
1. insects
2. soil
3. ocean
4. forests
The correct answer is:
3. ocean
The ocean is the largest living carbon sink on Earth. It absorbs and stores a significant amount of carbon dioxide from the atmosphere through a process called oceanic carbon sequestration. This helps to regulate the carbon cycle and mitigate the impact of excess carbon dioxide in the atmosphere. While soils and forests also play important roles as carbon sinks, the sheer size and capacity of the oceans make them the largest living carbon sink.
