Review the Table below:
Which of the following parts of the carbon cycle would be considered biological processes?
a
animal respiration
b
volcanic eruption
c
fossil fuel combustion
d
All the listed are considered biological processes.
The correct answer is a) animal respiration.
Animal respiration involves the release of carbon dioxide by animals during the process of cellular respiration. This is a biological process as it is carried out by living organisms.
Volcanic eruption (b) is not a biological process. It involves the release of carbon dioxide and other gases from deep within the Earth's crust during volcanic activity.
Fossil fuel combustion (c) is also not a biological process. It refers to the burning of fossil fuels such as coal, oil, and natural gas, which releases carbon dioxide into the atmosphere.
Therefore, only option a) animal respiration is considered a biological process in the carbon cycle.
The correct answer is:
d) All the listed are considered biological processes.
Explanation:
Biological processes in the carbon cycle involve living organisms and their interactions with carbon compounds. Animal respiration, where organisms exhale carbon dioxide, is a biological process. Additionally, fossil fuel combustion involves the burning of carbon-rich materials, which were once part of living organisms. Therefore, all the options listed in the table are considered biological processes in the carbon cycle.
To review the table and determine which parts of the carbon cycle are considered biological processes, we need to analyze the options provided.
a) Animal respiration: This refers to the process of animals breathing in oxygen and releasing carbon dioxide as a by-product. Since it involves living organisms, it is a biological process.
b) Volcanic eruption: This refers to the release of carbon dioxide from volcanic activity. Volcanoes are geological features, not biological organisms, so this process is not considered biological.
c) Fossil fuel combustion: This refers to the burning of fossil fuels such as coal, oil, and natural gas. Although it involves carbon-based materials from ancient biological organisms, the actual combustion process is not biological.
d) All the listed are considered biological processes: This option is incorrect since volcanic eruption and fossil fuel combustion are not considered biological processes.
Based on the analysis above, the only part of the carbon cycle that is considered a biological process is animal respiration (option a).
