Also rust.

• “Not alive”: Rust isn't a living organism, but it can spread across metal surfaces.
• “Can grow”: Rust expands and spreads over time, especially with exposure to air and moisture.
• “Needs air”: Oxygen is necessary for the oxidation process that creates rust.
• “Water kills me”: While water accelerates rusting, too much water can saturate the surface, slowing or preventing further rust development.

• Rust is a chemical process that happens when iron or steel reacts with moisture and oxygen.
• Rust doesn’t grow in the sense implied by the puzzle; it forms as a result of oxidation.
• Rust does not need air in the same way fire does; it requires moisture (water) and oxygen.
• Rust cannot be killed by water; in fact, water is one of the key components in the formation of rust.
