Answer is: <span>to convert solar energy into the chemical energy of sugars.
</span><span>Solar energy is stored in chemical bonds of sugars (glucose for example).
</span><span>In carbon dioxide, carbon has oxidation number +4 and in photosynthesis carbon gain electrons (solar energy), so
his oxidation number is lowered (reduced). Light energy is transformed
into chemical energy, that is stored in carbohydrate molecules
(glucose), which are synthesized from carbon
dioxide and water.</span>
Answer:
Explanation:
Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too. Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground.

Missing question:
(a) 1s2 2s2 2p6 3s1
(b) 1s2 2s2 2p6 3s2
(c) 1s2 2s2 2p6 3s2 3p1
(d) 1s2 2s2 2p6 3s2 3p4
(e) 1s2 2s2 2p6 3s2 3p5
Answer is: a) 1s²2s²2p⁶3s¹ (sodium).
Sodium have the largest second ionization energy, because when he lost one electron(first ionization energy), he have stable electron configuration of noble gas neon (1s²2s²2p⁶), so sodium do not need to lost second electron, because he will have unstable electron configuration.
