What are the two reactions that take place in the process of photosynthesis?

light-dependant reactions and Calvin cycle:)

Explanation:

Well, In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water.

hydrogen is a compound or a single element and a element is a pure substence that cannot be separated into simpler subtances

clorine is a compound its a chemical substance that forms when two or more different elements combine

so both hydrogen and clorine are compounds

b. climate change will cause an increase in biodiversity of all ecosystems.
