Answer:
The correct answer will be- non-living.
Explanation:
The rust is a chemical compound formed through a process called rusting by the oxidation of iron in the presence of air and water.
The formation of rust is a chemical process or a metabolic process which leads to the corrosion of iron and iron erodes away or rust eats the iron. It is not considered a living reaction as it lacks other features of living beings like not takes place in a cell as well not a heredity feature.
Thus, non-living is the correct answer
Rust eating a hole in a metal bucket is a nonliving process, as the answer to the question indicates. Iron, an element present in nature, is oxidised to make rust.
When iron is exposed to oxygen and moisture, it is created. Rust is not a living thing and cannot move, develop, or reproduce on its own. It is only a type of iron that is lifeless. A chemical interaction between the metal and oxygen causes rust to chew a hole in a metal bucket.
Rust is the result of the metal's reaction with oxygen to produce iron oxide. There is no need for a living thing for this response to take place because it is not alive. It is only a nonliving chemical process.
