- 1.
What is the primary source of carbon dioxide (CO2) release into the atmosphere?
- A.
Volcanic eruptions
- B.
Human activities
- C.
Photosynthesis
- D.
Forest fires
Correct Answer
B. Human activitiesExplanation
The primary source of carbon dioxide (CO2) release into the atmosphere is human activities, such as burning fossil fuels (coal, oil, and natural gas) for energy, deforestation, and industrial processes.Rate this question:
-
- 2.
Which process removes carbon dioxide from the atmosphere?
- A.
Combustion
- B.
Respiration
- C.
Photosynthesis
- D.
Decomposition
Correct Answer
C. pHotosynthesisExplanation
Photosynthesis is the process that removes carbon dioxide from the atmosphere. During photosynthesis, plants and other photosynthetic organisms use carbon dioxide, water, and sunlight to produce glucose (a form of sugar) and oxygen.Rate this question:

What is the role of oceans in the carbon cycle?
- A.
Absorb CO2
- B.
Release CO2
- C.
Absorb oxygen
- D.
Release oxygen
Correct Answer
A. Absorb CO2Explanation
Oceans play a vital role in the carbon cycle by absorbing carbon dioxide from the atmosphere. This absorption helps regulate the levels of CO2 in the atmosphere and acts as a carbon sink.Rate this question:
-
- 4.
Which gas is released during the process of photosynthesis?
- A.
Oxygen (O2)
- B.
Carbon dioxide (CO2)
- C.
Nitrogen (N2)
- D.
Methane (CH4)
Correct Answer
A. Oxygen (O2)Explanation
Oxygen is released during the process of photosynthesis. As plants and other photosynthetic organisms convert carbon dioxide and water into glucose, they release oxygen as a byproduct.Rate this question:
-
- 5.
What happens when carbon dioxide levels rise in the atmosphere?
- A.
Global cooling
- B.
Acid rain
- C.
Global warming
- D.
Increased ozone
Correct Answer
C. Global warmingExplanation
When carbon dioxide levels rise in the atmosphere due to human activities like burning fossil fuels, it leads to an enhanced greenhouse effect. This causes global warming, as more heat is trapped in the Earth's atmosphere, leading to changes in climate patterns.Rate this question:
-
- 6.
Which organism plays a crucial role in the oxygen cycle?
- A.
Plants
- B.
Fish
- C.
Bacteria
- D.
Insects
Correct Answer
A. PlantsExplanation
Plants, through the process of photosynthesis, play a crucial role in the oxygen cycle. They produce oxygen as a byproduct of converting carbon dioxide and water into glucose.Rate this question:
-
- 7.
Which human activity contributes significantly to deforestation, impacting carbon and oxygen cycles?
- A.
Mining
- B.
Agriculture
- C.
Recycling
- D.
Solar energy
Correct Answer
B. AgricultureExplanation
Agriculture, particularly large-scale farming and the expansion of agricultural land, is a major driver of deforestation. Forests are cleared to make way for crops and livestock, leading to the loss of trees that absorb carbon dioxide and release oxygen. This disrupts the carbon and oxygen cycles, contributing to climate change and impacting the balance of gases in the atmosphere. While mining can also cause deforestation, its impact is generally less extensive than that of agriculture. Recycling and solar energy are environmentally friendly practices that do not contribute to deforestation.Rate this question:

- 8.
How do forests influence the carbon cycle?
- A.
Absorb CO2
- B.
Release CO2
- C.
Absorb oxygen
- D.
Release oxygen
Correct Answer
A. Absorb CO2Explanation
Forests influence the carbon cycle by absorbing carbon dioxide from the atmosphere during photosynthesis. They store the carbon in their biomass and soil, acting as carbon sinks.Rate this question:
-
- 9.
Which process converts organic carbon into carbon dioxide?
- A.
Cellular Respiration
- B.
Decomposition
- C.
Photosynthesis
- D.
Erosion
Correct Answer
A. Cellular RespirationExplanation
Cellular respiration is the process that converts organic carbon (from dead plants and animals) into carbon dioxide. During cellular respiration, organisms use oxygen to break down organic molecules, such as glucose, to produce energy for their cellular activities. As a result of this process, carbon dioxide is released as a byproduct and returned to the atmosphere.Rate this question:
-
- 10.
What is the role of the atmosphere in the carbon-oxygen interaction?
- A.
Absorb CO2
- B.
Release CO2
- C.
Absorb oxygen
- D.
Release oxygen
Correct Answer
D. Release oxygenExplanation
During photosynthesis, plants and other photosynthetic organisms use carbon dioxide and water, along with sunlight, to produce glucose (a form of sugar) and oxygen. This process occurs in the presence of chlorophyll, which is a pigment found in the chloroplasts of plant cells.Rate this question:
