How does the alternation of generations in cnidarians impact their reproductive cycle and life cycle?
The alternation of generations in cnidarians involves two different stages in their life cycle: a polyp stage and a medusa stage.

This cycle helps cnidarians adapt to different environments and maximize their reproductive success.

Hydra - the polyp, anchored with a stalk, tentacles up; and medusa, the jellyfish, swimming free, tentacles down.

Anemones have a tiny jellyfish dispersal stage, and jellyfish have a tiny polyp reproduction stage.
