Watch out for so-called tree experts who do not understand tree
biology.
Storms, fires, floods, earthquakes, tornado's, volcanic eruptions and
other
abiotic forces keep reminding humans that they are not the boss.

The table I mentioned above (the one in Campbell & Reece) has is
titled "Plant Nutrients" and it has two columns. The first is divided
into two subsections, titled macronutrients and micronutrients.
Nitrogen, for example, is listed as a macronutrient. The second column
is titled, "Form available to plants." When we look there, we see the
(macro)nutrient nitrogen is available not as N or even N2, but only as
NO3- or NH4+. So the plants cannot absorb elemental nitrogen (the
common atmospheric form of which is N2) but they must get their
nitrogen as either nitrate or ammonia.

Note the difference between humans and plants here. Human nutrients
are commonly listed (and I have taught nutrition as well as General
Biology) as energy, protein, carbohydrate, lipid, water, minerals, &
vitamins.
God help your students. So what kind of energy are we talking here,
kinetic or potential?

Define element

define nutrient

define food

Define wise.

Wrong answer.
