- A Birds, which swallow the seeds whole and disperse them in droppings
- B Ants (myrmecochory -- ants carry seeds to their nests, dispersing them)
- C Wind currents that carry the lightweight seed structures
- D Water currents that float the seeds downstream
Correct answer: B. Ants (myrmecochory -- ants carry seeds to their nests, dispersing them)
Explanation: Elaiosomes: lipid-rich seed appendages. Ants collect seeds for elaiosomes (food reward), carry them to nests, eat the elaiosome, and discard the viable seed -- dispersal by ants (myrmecochory).
