Answer:
Sun(solar energy)
Explanation:
The sun is the ultimate source of energy in our solar system.
The chemical energy in plants all started out with solar energy from the sun.
During the process of photosynthesis;
- green plants manufactures their food using sunlight.
- in the presence of this solar energy, they combine carbon dioxide and water to produce glucose and oxygen.
Photosynthetic reaction simply converts solar energy from the sun into chemical energy.
Almost all animals obtain their own energy needs from the plants converting the chemical energy into other forms of energy.

Answer:
Explanation:
The structure represented in the picture attached to the question is a benzoic acid (which is an organic compound).
8. The type of bond present between the carbon-carbon, carbon-hydrogen and carbon-oxygen atoms in the compound (same as other organic compounds) is a covalent bond. This is because oxygen and hydrogen share there valence electrons with carbon; oxygen has two valence electrons and thus it is surrounded with two bonds and hydrogen has one valence electron and thus surrounded with one bond.
9. The elements present in this compound, as can be seen in the picture, are carbon, hydrogen and oxygen which is the reason it is referred to as an organic compound.
10. The chemical formula of this organic compound is C₆H₅COOH. The "cyclic" structure (aromatic structure) there shows that it is a derivative of benzene (because of the presence of the alternating double bonds) while the carboxylic group there has to be written separately in the formula.
