The seeds of certain plants fail to germinate if they do not pass through the digestive tract of fruit-eating birds. This is due to A) hibernation B) seed coat impermeability C) infertility D) vegetative reproduction
Option B) A dormant seed is one that is unable to germinate in a specified period of time under a combination of environmental factors that are normally suitable for the germination of the non-dormant seed. Dormancy is a mechanism to prevent germination during unsuitable ecological conditions, but the probability of seedling survival is low.
