Is rust eating a hole in a metal bucket living or nonliving?

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

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
