Answer 2

Mangrove forests disperse their seeds through a variety of methods such as water dispersal, floatation, and germination while still attached to the parent tree. Some species have specialized adaptations to aid in seed dispersal, such as pneumatophores that help prop roots above water to facilitate seed dispersal by floating.
