Ants Can Move a Papaya Tree Plant

I noticed the ants on my balcony were moving a papaya seed that had germinated in my compost bin. Out of all the seeds in the compost, only this one particular one had a fair number of ants around it. It seemed that they were trying to move it. To where and why I have no idea. Wonder if the fact that it's germinating has anything to do with their interest. Maybe they want a papaya tree in their nest.
