Where do photosynthetic organisms get the energy needed to make sugars during the light-independent/dark reactions?

Responses

They obtain the energy directly from the Sun.

Photosynthetic organisms get the energy needed to make sugars during the light-independent reactions (also known as the Calvin cycle) by using the ATP and NADPH that are produced during the light-dependent reactions. So, the correct response is:

They use the ATP and NADPH that are produced during the light-dependent reactions.
