Explanation:

- Fish: ?? Fish are considered a renewable resource as they can replenish their populations through reproduction. Responsible management and sustainable fishing practices ensure their longevity.

- Coal: This is a non-renewable resource. It forms over millions of years and cannot be replenished on a human timescale once used.

- Petroleum: Similar to coal, petroleum is a non-renewable resource, taking millions of years to form and not replaceable once depleted.

- Iron-ore: This is also classified as a non-renewable resource. While we can recycle metals, the original ore is finite.
