Resources that can be replenished over a relatively short time span are called

fossil fuels
nonrenewable resources
mineral resources
renewable resources

renewable resources

Explanation:

Resources are substances that are used to produce energy.

They can either be 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 fossil fuels like coal, mineral resources.

Crops, as mentioned earlier, are a renewable resource.

Crops can be grown again and again. Also, crops are renewable as long as the soil is available for its growth. Appropriate soil provides ideal platform for growth of different types of plants.

Soil along with weather conditions like rain, are renewable resources. They will be available as long as the planet Earth exists. This makes replenishment of plants easier.

Also, crop harvesting is a continuous process. Once the harvested crop is sold, another harvest of the crops is begun. Hence, this makes the crops available due to faster replenishment.

Hence, crops, along with soil and rain, are a renewable resource as long as it can be grown again and as long as the soil is available. Also, ideal conditions which favour crops will be available till the planet Earth exists.

Fossil fuels are non renewable resources since they are available for a finite period of time.

Mineral resources are non renewable resource since they are available for a finite period of time.

Both fossil fuels and mineral resources will perish once they are consumed completely and their replenishment takes a long period of time. Hence, the unavailability of both fossil fuels and mineral resources will be as long as the replenishment takes place.

gametes or germ cells are haploid cells (example: sperm and ova) containing only one set (or n) number of chromosomes and autosomal or somatic cells are diploid cells containing 2n number of chromosomes.
