Explanation:

Resources can be either renewable or non renewable.

Renewable resource can be defined as the resources which have long availability or faster replenishment as compared to the consumption rate of the resource or both.

Examples include air, soil, plants, animals and others.  

Alternatively, non renewable resource refers to the resources which are available for a limited amount of time or whose replenishment is slower as compared to its consumption rate or both.

Examples include coal, oil.

Wheat crop is both a renewable and a non renewable resource.

Wheat crop can be grown again and again. Also, wheat crop is renewable as long as the soil is available for its growth. Appropriate soil provides ideal platform for growth of wheat plants.

Hence, it is a renewable resource as long as it can be grown again and as long as the soil is available. Also, ideal conditions which favour wheat crops need to be available.

Wheat crop is available for a limited period of time after which it can become useless. Also, wheat crops can be destroyed before they can be consumed. Limited availability can be due to shorter usefulness of the crops after which they become non usable. Other reason for low availability is that the crops can be damaged before they can be harvested for use.

Thus, it is also a non renewable resource.

Sea water is a renewable resource since it is available for infinite period of time.

Solar energy is a renewable resource since it is available for infinite period of time.

Iron ore is a non renewable resource since it is not available for infinite period of time. This will perish when it is consumed completely and its replenishment takes a long period of time. Hence, it will be unavailable as long as it is not replenished.
