Which statement correctly describes a part of the carbon cycle?
A
Carbon dioxide is converted into oxygen by the ocean.
B
Plants absorb carbon dioxide during photosynthesis to produce glucose.
C
Fossil fuels are formed by the immediate decomposition of dead organisms.
D
Animals release carbon dioxide during photosynthesis.
Verified step by step guidance1
Begin by understanding the carbon cycle, which is the process by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.
Recognize that photosynthesis is a key part of the carbon cycle. During photosynthesis, plants absorb carbon dioxide (
) from the atmosphere.
Understand that during photosynthesis, plants convert carbon dioxide and water into glucose (
) and oxygen (
). This process is crucial for the survival of plants and the production of oxygen for other organisms.
Clarify that fossil fuels are formed over millions of years from the remains of dead organisms, not by immediate decomposition. This involves complex geological processes.
Note that animals do not release carbon dioxide during photosynthesis; instead, they release carbon dioxide during respiration, which is the process of converting glucose and oxygen into energy, carbon dioxide, and water.
