How did the use of groundwater change from preindustrial times to industrial times?
a. groundwater use decreased from preindustrial times to industrial times.
b. groundwater use increased from preindustrial times to industrial times.
c. groundwater use remained virtually the same from preindustrial to industrial times. d.groundwater was not used during preindustrial times.

The correct answer is option b.

Explanation:

The water sources, which are found underneath the ground in sand, rocks, and soils is known as the groundwater. The amount of groundwater, which was used at the time of the pre-industrial period was very small in comparison to the amount used at the time of industrial times.  

This has resulted in a substantial reduction in the concentration of groundwater available at the present time. Other elements, which had resulted in a decline in the level of groundwater comprise a lack of precipitation and an increase in the rate of pollution.  

the food storage products of chrysophytes are oils or the polysaccharide laminarin.   formerly classified as plants, the chrysophytes contain the photosynthetic pigments chlorophyll a and c all but the yellow-green algae also contain the carotenoid pigment fucoxanthin.
