(a)
what is the process of chemosynthesis
none of these are correct
light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
the process by which green plants and certain other organisms transform light energy into chemical energy.
Process by which some organisms, such as certain bacteria, use chemical energy to produce carbohydrates, like plants
Examine the illustration of the photosynthesis equation. How does the equation relate to both photosynthesis and cellular respiration, and what is the connection between the two processes?
Photosynthesis utilizes energy to build carbohydrates, while cellular respiration metabolizes carbohydrates.
Photosynthesis utilizes energy to metabolize carbohydrates, while cellular respiration builds carbohydrates.
Photosynthesis and cellular respiration both utilize carbon dioxide and water to produce carbohydrates.
