HELP QUICKKK Which soil layer in the diagram above has the MOST nutrients available for plants growing in the soil?

I would think layer 2, or 3 because in layer 1 the plant has already used that nutrients and it doesn’t replenish fast enough and in layer four there are a lot of rocks that would make it possibly hard for the plant to grow further and the nutrients would prolly be used up possibly too.

Hope this helps

answer: c. the experiment shows that the red substance experienced a chemical change.

explanation: chemical change is the change in which chemical composition of the substance changes. physical change is the change in which there is no change in chemical composition.

chemical changes are accompanied by following changes:

a) precipitate formation

b) energy is released or absorbed

c) formation of bubbles

d) change in color

as it is given that the red color has disappeared and there is production of gas, it means the red substance has undergone a chemical change.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
