How will the ampunt of fertilizer used on the field affect the number of earrhworms found there

Generally fertilizers increase earth worm numbers if the PH of the soil is kept near neutral.

c is the answer because when something is left after something evaporates that shows the chemical change.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
