Ah. The algae gets...eaten.
lots of info here.
the short version is that at birth, the slugs eat some of this aglae and suck out the soft center out of the filamentous algae, and somehow separate the chloroplasts from the rest of the cell. Then they integrate the chloroplasts into their gut lining and the chloroplasts do their thing and make food.
Normally, the chloroplasts would die shortly thereafter because the chloroplasts lack the proteins needed for complete chloroplast upkeep, but the slugs have somehow acquired the genes needed to make those proteins, so they an actually maintain the chloroplasts.

Hm, so the sea slug receives energy from the algae
but what do the algae get in return ?
