algae
Let an agent explain algae by group and role, address harmful algal blooms and safety, describe uses and cultivation, and support identification and education.
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 algae by group and role, address harmful algal blooms and safety, describe uses and cultivation, and support identification and education.
A diverse informal group of photosynthetic, mostly aquatic organisms ranging from single-celled microalgae and snow algae to large seaweeds, not forming a single evolutionary lineage; algae produce much of the world oxygen, form the base of aquatic food webs, and are used as food, feed, fertiliser and biofuel, while some form harmful blooms.
What it is for: Ecology, food, industry and environmental monitoring.
It can be identify major algal groups; explain ecological roles; advise on harmful bloom safety; describe uses and cultivation.
