Carbon dioxide is obtained from the air and changed into carbohydrates and oxygen during the process of
A. Fossilization
B. Respiration
C. Digestion
D. Photosynthesis
Is the answer D?
Thanks
Looks good to me.
Yes, the correct answer is D. Photosynthesis. To arrive at this answer, you need to understand the process described in the question and then eliminate the other options.
Photosynthesis is the process by which green plants, algae, and some bacteria convert carbon dioxide from the air into carbohydrates (such as glucose) and oxygen. In this process, plants use sunlight energy to convert carbon dioxide and water into glucose and oxygen. The glucose produced during photosynthesis serves as a source of energy and carbon for the plant.
Fossilization is the process in which the remains of dead organisms, such as plants and animals, are preserved in rock over a long period of time. Fossilization does not involve the conversion of carbon dioxide into carbohydrates and oxygen.
Respiration is the process by which living organisms obtain energy from glucose (or other organic molecules) by combining it with oxygen. In respiration, oxygen is consumed, and carbon dioxide is produced. So, it is the opposite process of photosynthesis.
Digestion is the process by which large organic molecules, such as carbohydrates, proteins, and fats, are broken down into smaller molecules in order to be absorbed and utilized by the organism. It does not involve the conversion of carbon dioxide into carbohydrates and oxygen.
Therefore, the correct answer is D. Photosynthesis.
