I know that the amount of worms affect the dead plant and the dirt because in the 3rd day, in the jar with 4 worms, the raspberry get smaller and there was less dirt. This means that if there more worms, it effect the dead plant and I think that the worms eat the dirt (whatever the worms have grown). In the 5th day, also, the raspberry get smaller and there was even less dirt, and the worms grows.
