Answer 4

Well, the word itself provides a big clue.........

Photosynthesis is the process by which plants, some bacteria, and some protistans (algae, molds) use the energy from sunlight to produce sugar, which cellular respiration converts into ATP, the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy, is associated with the actions of the green pigment chlorophyll. The total reaction is astonishingly simple:

6H2O + 6CO2 ----------> C6H12O6+ 6O2

Answer 5

Mainly its light, which excites electrons, which give their energy to reduce electron carriers, which in turn give their energy to molecules which are gradually reduced to form glucose.

Answer 6

the sun because... it is.
