Because seed condition and escape from distance‐dependent seed predation are two primary ways dispersal benefits plants, we conducted a field experiment comparing seed predation (i.e., ratio of seed removal) between whole fruit (simulating a frugivore absent situation similar to that on Guam), gut‐passed seeds, and depulped seeds close to and distant from adult chili plants. Well, it is when the animals are eating the seeds as fruits or directly, and then they dispose it by about feces. Our educator team will work on creating an answer for you in the next 6 hours.

As another example, many animals eat fruits, and then travel a long distance before they poop out the seeds. The fact that the papaya plants disperse their seeds by animals ensures that they are not going to be too close together and that two plants which are 'related' are going not going produce seeds together as these are not going to be the best papaya plants which can be grown.
