Question 116

Which descriptions fit seeds that are dispersed by animals? Select all that apply.

  1. They sit inside a juicy fruit that is eaten and later passed outCorrect answer
  2. They have wings that make them spin as they fall
  3. They are broken down by the animal that eats them
  4. They are flung out when a dry pod splits open
  5. They are carried on fur by hooks on the outside of the fruitCorrect answer

Explanation

Animals move seeds in two ways: they swallow a fleshy fruit and leave the seeds somewhere else later, or they brush past a fruit that catches on their coat and carry it until it drops. The claim about digestion gets the outcome wrong, since a seed that makes the journey has a coat tough enough to survive it, and a seed broken down inside an animal would disperse nothing.
