Based on the provided information on 'Dispersal by Animals', which of the following statements are true about animal-mediated seed dispersal mechanisms? Select all that apply

  • A: Seeds can be dispersed through an animal's digestive system after consuming edible fruits.
  • B: Some seeds possess structures like sharp spines that allow them to attach to animals for transportation.
  • C: Animals may inadvertently aid in dispersal by burying seeds for storage, which can later germinate if forgotten.
  • D: Ants are primarily attracted to seeds by their hard, protective outer coatings, which they use for nest building.

Explanation

The text describes: A seeds in edible fruits dispersed in feces e.g., black bear ; B sharp, tack-like spines on puncture vine fruits that attach to animals; and C animals like squirrels hoarding seeds in caches, which can germinate if forgotten. Option D is incorrect because ants are attracted by nutrient-rich 'food bodies,' not the hard coating itself.
