heterotroph
Let an agent explain heterotrophy and its kinds, relay classification and ecological roles from biology references, describe examples across the tree of life, and distinguish heterotrophs from autotrophs and mixotrophs.
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 heterotrophy and its kinds, relay classification and ecological roles from biology references, describe examples across the tree of life, and distinguish heterotrophs from autotrophs and mixotrophs.
An organism that cannot produce its own food from inorganic sources and must obtain organic carbon by consuming other organisms or their products, including all animals, fungi, most bacteria and archaea, and non-photosynthetic protists, classified by energy and carbon source as chemoheterotrophs or photoheterotrophs and by feeding mode as herbivores, carnivores, omnivores, detritivores, decomposers and parasites; heterotrophs occupy the consumer and decomposer levels of food webs and depend ultimately on autotrophs.
What it is for: Not applicable; a nutritional category.
It can be explain the concept and kinds; relay ecological roles; describe examples; distinguish from autotrophs.
Distinguishing features
Organic carbon dependence
Consumer role
Diverse feeding modes
Spans all domains
What it looks like
Not a visible object; animals, fungi and many microbes.
Physical character
share of described species that are heterotrophs: large majority share - animals and fungi dominate counts
How it is recognised
Organism consuming organic carbon
Chemoheterotrophs and photoheterotrophs; herbivores, carnivores, decomposers, parasites
Autotrophs fix carbon; mixotrophs do both
