A

B
Photosynthesis in algae
C
Decomposition by fungi
D
Nitrogen fixation by bacteria
Verified step by step guidance1
Understand the question: The problem asks about the process in the biosphere that moves water from the geosphere (land) to the atmosphere. This involves understanding the role of living organisms in the water cycle.
Review the water cycle: Water moves through various processes such as evaporation, condensation, precipitation, and transpiration. Transpiration is the process where plants release water vapor into the atmosphere through small openings in their leaves called stomata.
Analyze the options: Evaluate each option to determine which one involves the movement of water. 'Transpiration by plants' directly involves water movement, while the other options (photosynthesis, decomposition, nitrogen fixation) are unrelated to water transfer to the atmosphere.
Connect the biosphere to the water cycle: Plants, as part of the biosphere, absorb water from the soil (geosphere) through their roots. This water is then released as vapor into the atmosphere during transpiration, contributing to the water cycle.
Conclude the correct answer: Based on the explanation, the process that best describes the movement of water from the geosphere to the atmosphere facilitated by the biosphere is 'Transpiration by plants.'
