Question

which life cycle has a life cycle that includes both spawning -> larave -> a benthic polyp that forms a colony -> budding -> juvenile -> adult?
anemone
cuttlefish
jellyfish
squid

Explanation:

Anemones have a simple life cycle without the polyp - colony - budding stage. Cuttlefish and squid have more complex, non - polyp based life cycles. Jellyfish (in the phylum Cnidaria) have a life cycle that includes spawning (release of gametes), formation of larva (planula), settlement to form a benthic polyp (scyphistoma) which can form a colony, budding (to produce ephyrae), and then development to juvenile and adult jellyfish (medusa).

Answer:

jellyfish
