It is mined for minerals (salt, sand, gravel, and some manganese, copper, nickel, iron, and cobaltcan be found in the deep sea) and drilled for crude oil. The ocean plays a critical role in removing carbon from the atmosphere and providing oxygen.

The human body has living cells that interact with other living cells (Food) and inorganic cells (Salt, Oxygen). It also has a lot of chemical reactions that simultaniously happen inside of it.
Inorganic systems usually do not interact with themselves, and the reactions are mostly exterior.
Wood, when dry, stores chemical energy. This chemical energy is released as the wood burns, and it is converted into heat, or thermal energy. This also produces light energy. As a result of burning, the wood turns into an entirely new substance - ashes. Wood, a form of fuel with lots of potential energy stored in its covalent bonds, will react with molecules of oxygen in the air in a dramatic chemical reaction we call fire. The complex molecules in the wood have 'high energy' covalent bonds, as do the molecules of oxygen.
I hope this helped:))
