What source of carbon for carbon fixation?
The primary source of carbon for carbon fixation in plants is carbon dioxide (CO2) from the atmosphere. In photosynthesis, plants use the enzyme RuBisCO to fix CO2 into organic molecules, eventually producing glucose for energy.
What was the primary source of CO2 in the Earth's early atmosphere?
Volcanic activity was the primary source of CO2 in the Earth's early atmosphere. During this time, volcanic eruptions released large amounts of gases, including carbon dioxide, into the atmosphere.
What is the difference between a carbon source and a carbon sink in the context of the carbon cycle?
In the carbon cycle, a carbon source releases carbon dioxide into the atmosphere, while a carbon sink absorbs and stores carbon dioxide from the atmosphere.
Which increase the amount of carbon dioxide in the atmosphere acting as a carbon source?
Respiration :)
Which increases the amount of carbon dioxide in the atmosphere acting as carbon source?
Respiration :)
Which increases the amount carbon dioxide in the atmosphere acting as a carbon source?

What is a plant's primary source of carbon?
A plant's primary source of carbon is the air, where carbon is found in the form of carbon dioxide. Plants also need carbon dioxide, water, and light energy for photosynthesis that occurs in plant leaves.
What is a natural source of sulfur dioxide carbon dioxide and ash in the atmosphere?
Volcanic eruptions are a natural source of sulfur dioxide, carbon dioxide, and ash in the atmosphere. During an eruption, gases such as sulfur dioxide and carbon dioxide are released from the magma, along with ash which is a mixture of fine rock particles and gases.
Which increases the amount of carbon dioxide in the atmosphere acting as a carbon source?

Can you identify whether each process is a carbon source or a carbon sink?
A carbon source is a process that releases carbon dioxide into the atmosphere, while a carbon sink is a process that absorbs and stores carbon dioxide.
The primary source of oxygen for the earth's atmosphere?
The primary source of oxygen in Earth's atmosphere comes from photosynthesis by plants, algae, and some bacteria. During this process, these organisms use sunlight to convert carbon dioxide and water into oxygen and glucose. This oxygen is then released into the atmosphere as a byproduct.
Main source of carbon dioxide in the ocean?
the atmosphere is the main source of CO2 in the ocean
