nutrient
Let an agent explain nutrients and their classes for humans, animals and plants, relay requirements, sources and roles from nutrition and agricultural science, describe essential nutrients and soil nutrients, and distinguish nutrients from foods, supplements and marketing terms, without giving personal dietary advice.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain nutrients and their classes for humans, animals and plants, relay requirements, sources and roles from nutrition and agricultural science, describe essential nutrients and soil nutrients, and distinguish nutrients from foods, supplements and marketing terms, without giving personal dietary advice.
A substance that an organism uses to survive, grow and reproduce, taken in from the environment or diet, including macronutrients such as carbohydrates, proteins, fats and water, micronutrients such as vitamins and minerals, essential nutrients that the body cannot make, soil nutrients such as nitrogen, phosphorus and potassium for plants, storage compounds in seeds and tissues, and related dietary components such as prebiotics that feed gut microbes; the term glyconutrients is a marketing label without accepted scientific basis.
What it is for: Sustaining life and growth.
It can be explain classes; relay requirements and roles; describe soil nutrients and prebiotics; distinguish related terms.
Distinguishing features
Required for life
Macro and micro classes
Essential versus non-essential
Human, animal and plant senses
What it looks like
Not a visible object; substances in food, soil and water.
Physical character
essential amino acids for humans: 9 count
vitamins: 13 count - recognised
primary plant macronutrients: N, P, K list
How it is recognised
Substance used by organisms to live and grow
Macronutrients, micronutrients, essential nutrients, minerals, soil nutrients, storage compounds, prebiotics
Foods contain nutrients; supplements concentrate them; glyconutrients is a marketing term

- How should nutrition and agricultural sources be linked?
- The registry entry has a merged alias naming a marketing term; should it be flagged or removed?
