Question

Select the process that occurs in dark reaction.

(1) Light energy is converted into chemical

energy

(2) Water splits into hydrogen and oxygen

(3) Hydrogen is added to carbon dioxide

(4) Oxygen is evolved​

Answer 1

Answer:

(2)

Explanation:

The dark stage of photosynthesis is an intricate process where NADPH and ATP are used to produce carbohydrate molecules (or sugars). ... Through the splitting of water molecules, the chemical energy released is used to synthesise two basic molecules of plant metabolism

Answer 2

Answer:

1) Light energy is converted into chemical energy is the right option .

Explanation:

Dark reaction is also called as carbon fixing reaction . It is a light - independent process in which sugar molecules are formed the CO2 and water molecules. The dark reaction is also called as Calvin cycle . Actually there are two main types of reactions namely light reaction and carbon fixing reaction ( dark reaction ) . So based on your question I'll gave the answer . Hope so it will give you the better understanding of the concept , happy to help !
