Question

Which of the following elements are obtained by plants from the soil?

oxygen
nitrogen
hydrogen
phosphorus
potassium

Answer 1

Alright.

Plants get their Oxygen and Carbon from the air.
We know that.

I don't know about Hydrogen,
but I think that they can get that by breaking apart water molecules. (Because water has hydrogen.)

That leaves Nitrogen, Phosphorus, and Potassium.
They get THOSE three elements, from the soil.
