I do not know what you mean when you say nutrient? Are you referring to
essential elements? A tree cannot absorb a nutrient, rather they absorb
elements. Not nutrients.

I am afraid you don't know what you're talking about. My copy of
_Biology_ by Campbell & Reece (7 ed., pretty much the standard
university general bio textbook) lists these forms of nutrients as
they are available to plants (note that the nutrients listed ARE
elements- but most are not available to plants in elemental form):

Nutrient Form available to plants

Carbon CO2
Oxygen CO2
Hydrogen H2O
Nitrogen NO3-, NH4+
Phosphorus H2PO4-, HPO4(2-)
Sulfur So4(2-)
Boron H2Bo3-
Molybdenum MoO4(2-)



Elements are single groups of atoms of the same
kind such as calcium and nitrogen. Nutrients are substances that contain
the essentials for life, in the best amounts.

Nonsense. Consider humans: we require energy, hydrogen, and oxygen.
Lipids are nutrients. By your logic, a saturated fat is the best
possible source of energy, oxygen and hydrogen, since it contains more
of those than an unsaturated fat.

Saturated refers to double or triple bonds, usually carbon bonds, not
saturation of atoms, or energy.

There's no best or worst here-
things are more or less nutritious, but if something is not as
nutritious as something else, that doesn't disqualify it.

Nutrients contain an energy
source,
The energy source is the sun which. Bio-mass contains bond energy but it
may or may not be accessible to human consumption. Hell, rocks contain
energy in the form of bonds. Every substance and wave has enrgy but few
of them are human or tree nutrients.
elements, vitamins, and other essentials for life. PLANTS CANNOT

Nonsense. Energy IS a nutrient. Elements ARE nutrients. Vitamins ARE
nutrients.
A nutrient may contain bond energy that can be exploited by a
metabolism, but not all energy is a nutrient. E=M(CxC).


ABSORB NUTRIENTS. Saying you feed plants with plant food, calling
fertilizers food, and saying that plants absorb nutrients indicate an
absolute ignorance of photosynthesis!!

Um, someone around here is ignorant, for sure.

Elements are single groups of atoms
of the same kind such as calcium and nitrogen.
A nutrient is a substance that contains an element with an energy source
and

Vitamins contain no energy source. Did you know that? The majority of
enzymes function as coenzymes and are needed to catalyze particular
biochemical reactions. Water is a nutrient, yet provides no energy.

an element without. Nitrogen is NOT a nutrient for chlorophyll containing
trees.

You're nuts. Nitrogen is a macronutrient- it is needed in large
quantities.

A substance that is very high in elements and energy it is called a
nutrient. To make this clear, please allow me to share this with you.
Essential elements. Look at your chart of Atomic Properties of elements.
(Not the Atomic Properties of nutrients) That's where you will find your
elements.

If you look on page 373 in Merriam-Webster's Collegiate® Dictionary, Tenth
Edition you will find a list of Chemical Elements as well as symbols,
atomic
numbers and atomic weight.

Try cracking a general biology book.

Chris

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. Plants do not need the more complex forms of these
substances, and require particular elements- but those elements must
be in particular forms to be absorbed. Humans need minerals (that
contain particular elements) and we need to have them in a particular
form to be USED, not just absorbed. Granted, there's some leeway in
that. But not all that much. We cannot digest large chunks of CaCO3,
nor do we absorb it very well, so if you're taking calcium
supplements, you much better off taking calcium citrate than calcium
carbonate- and for humans, calcium is indeed a macronutrient.

Before his untimely death, Neil Campbell was a pioneer in nutrient
transport in vascular plants. His text has been the standard general

dozen books as possible replacements at our school, and none even came
close in quality.

Thanks, I will take his ideas over yours. And I will say to you what
I always say to someone who exclaims, "The textbooks are

Excuse me? Um, first off, energy is not so simplistic, I am afraid.
There are more kinds of energy than kinetic or potential- you know
that, right? There's thermal energy, and electromagnetic radiation
(like X-rays) neither of which can be classified as kinetic or
potential energy.

But the answer to your question, of course, is that it's chemical
energy. Chemical bonds retain energy, and breaking those bonds
releases the energy. Lipids contain more of those bonds, and more high-
energy bonds, than do carbohydrates or proteins, hence there are more
Calories/gram in fats than in the other two nutrients.

The most dangerous form of malnutrition goes by the acronym PEM, for
protein-energy malnutrition. In PEM we see a deficiency both in
essential amino acids and in caloric intake. In children this leads to
kwashiorkor- the poor kids with the hugely swollen bellies (a result
of an inability to move liquids back into the blood), and in adults it
manifests as marasmus, or wasting, where we see the body mobilizing
lean muscle tissue for energy. But note the name- "energy

I must admit that my understanding of chemistry is very rudimentary at
this point. I wouldn't call it a complete ignorance, but I did pay
attention in my elementary science classes, for what that is worth.

I was referring nutrients as those substances which are required by an
organism to support itsself. also, I feel that Webter's definition of
nutrient is an oversimplification. Remember that the purpose of a
dictionary is to define language as it is used, not to dictate its use.

I am a bit limited in resorces, including time for study, as I am in
the middle of a disaster area, so it may be some time before I can
check out some of the references in these posts.

I looked up the wikipedia article on nutrients and it splits them into
substances which provide energy and substances which support
metabolism. The chemical elements of which you speak would fall under
one or the other of these groups. unfortunately, the article uses
confusing language in places and is severly lacking references. The
discussion thread for that article would probably be a better place to
hash out an exact meaning.

Anyway, I hope that my input can be of some use.

Let's see. Thermal energy requires a gradient, that is to say high
energy to low energy, in order to function. Allowing an object in a
high energy state to go to a lower energy state. That is called potential
energy. And you must have heard of Erwin Schrödinger and wave mechanics.
Can you say photon? Sure you can. It can be treated as a wave or a
particle. So what is all this crap? My response was to John, who has a

Synonyms for protein-energy malnutrition and related keywords:
protein-energy malnutrition, PEM, protein-calorie malnutrition,

Sorry Chris, counselors, or medical practitioners, nutritionists may be
but they aren't biologists, chemists, or physicists. Just because some
of them may use a term to define a condition doesn't mean that the term
is based in the hard sciences. The term may have meaning to them but is
meaningless to the greater scientific community.

Just bought a thesaurus, did you? (Now _that's_ a sneer.)


Sorry Chris, counselors, or medical practitioners, nutritionists may be
but they aren't biologists, chemists, or physicists. Just because some
of them may use a term to define a condition doesn't mean that the term
is based in the hard sciences. The term may have meaning to them but is
meaningless to the greater scientific community.

Well, as a professional biologist working in biology, I can assure you
that you're mistaken.

But you have a nice day.
