this map shows the amount of groundwater (gw) in parts of pakistan. farmers in pakistan once relied on rivers and canals for their water supply, but as cities expanded and
populations grew, more farmers used groundwater for their crops. when this map was made, there were no laws restricting how many wells could be built in pakistan to remove
groundwater.
what would be the best solution to pakistan conserve their water supply?
a.
increase the number of groundwater wells in all three regions.
b.
build more wells in region 3, and restrict building in all other regions.
c.
pass laws restricting well building in region 1, but increase wells in regions 2 and 3.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
