Answer:
The correct option is A. They provide the energy required to build high-energy sugars.
Explanation:
Calvin cycle can be described as the series of dark reactions of the process of photosynthesis.
During the Calvin cycle, carbon dioxide is reduced to glucose. The molecules of NADPH and ATP play an active role in this reaction to occur. The molecules of ATP serve as a source of energy. Whereas, the molecules of NADPH serve as a reducing agent. Electrons are added by NADPH so that carbon dioxide gets converted into glucose.
Answer:
Atmosphere
Explanation:
Phosphorus cycle in nature is a unique cycle compared to the other natural biological and chemical cycles such as the carbon, nitrogen, sulfur and water cycles, as there is no gaseous phase in the phosphorous cycle. Due to the prevailing atmospheric temperature and pressure which are not appropriate for the formation of gases associated with phosphorus, the compounds in nature where phosphorus can be found are not gases. Phosphorus can therefore be found majorly in sedimentary rocks.
Answer: The correct answer is choice D.
