Frage 115

A fruit is extremely light and carries a spreading tuft of fine hairs. Which method of dispersal do those features suit?

  1. Dispersal by animals that eat it
  2. Dispersal by animals that carry the fruit on their fur
  3. Dispersal by water, floating away from the parent
  4. Dispersal by wind, carried on the airRichtige Antwort

Erklärung

Low weight and a spreading tuft together slow the fall and let moving air carry the fruit well clear of the parent plant before it settles. Hooks are what catch on fur, and a tuft of soft hairs cannot hold onto anything, so a fine plume points to the air rather than to an animal as the carrier.
