Plants play a crucial role in the carbon cycle because they ?
A. Do not reléase carbón dioxide during celular respiration.
B. Allow carbon to enter an ecosystem through photosynthesis.
C. Have special bacteria that live in their root systems.
D. Are chemically converted into fossil fuels when burned.
Answer:
The correct answer is option B. Allow carbon to enter an ecosystem through photosynthesis.
Explanation:
During the carbon cycle, plants play a very important role.
Through a process called photosynthesis, the plants that are in our planet obtain the carbon dioxide that is in our atmosphere, and with the help of sunlight and water, these plants transform this carbon dioxide into oxygen and glucose.
All living beings use this glucose generated by plants and oxygen to survive.
The animals will then eat these plants and the carbon dioxide will become part of the atmosphere again, allowing this process to begin again.
