Question 5
Mahogany and hora bear their fruits at the apex of a tall tree. How does this help dispersal by wind?
The right answer is the one marked above.
It buys the same extra seconds of falling that a wing does. Height and a wing solve the same problem — the longer a seed stays in the air, the further sideways the wind can push it.
Letting the seeds fall straight down onto clear soil describes the opposite of dispersal: falling straight down is exactly what these adaptations exist to prevent. Producing a large quantity of seeds is the other wind adaptation, and it accepts that wind-scattering is a lottery by buying more tickets.
