The correct answer is an accumulation of microorganisms in deep marine environments.
Chalk rock refers to a pure form of limestone produced in tropical and warm seas about 100 million years ago in the Cretaceous period. The microscopic marine algae known as coccoliths thrived in the ancient seas. Their shells were comprised of calcite. With the death of the algae, their bodies sunk to the floor of the sea and sediment of chalk got deposited.
Over many years layers of chalk sediment got deposited and resulted in compaction of loose sediment into solid chalk rock.
The answer is: "global" .

Answer:
Spore
Explanation:
Most of the fungal species reproduce through spores. Spores are the reproductive structures of fungi that help in the survival of fungal species under unfavorable conditions and their dispersal to new habitats. Fungal spores are very light in weight and are dispersed with wind currents.
For example, ascospores are the sexual spores produced by fungal species of the group ascomycetes and are carried with the wind.
