Leeches suck blood and it was believed that leeches would actually suck the bad blood\diseased blood out of your body. Today leeches are used after reattachment of body parts, particularly fingers and toes. The leeches relieve the congestion of blood in the affected parts. The leeches also put a chemical into the blood in the area of the attachment that prevents blood from clotting.
I would be more willing to say that leeches are parasites, not predators.
Birds and moles that are immune to this and cannot be internally harmed by the leeches. Also, some fish may be immune to the leeches too, so they would also be able to eat them.
I would think that they will have food to eat.
Yes. There are insects which do help humans. Two examples of this are: leeches and maggots Honeybees and ladybugs..The honeybee pollinates crops and makes honey, the ladybug feeds on harmful insects. Leeches are not insects.
The answer will depend upon which bone you are talking about - a description or a picture would be helpful.
It would be very unusual for leeches to kill people, however, they do suck blood, and a person can die from blood loss. In order to lose that much blood, a person would have to be unconscious will leeches are feasting at will.
Most people would consider them helpful though there are people that think we rely on them too much

no that would be weird
Leeches primarily feed on the blood of other animals, including other leeches. While it is not common for leeches to feed on each other, it can happen if they are in close proximity and there is no other food source available.
They die because the momentum of the marsh helps them live and if they are destroyed therefore leeches would have nowhere to live and they would explode.
No, leeches require oxygen to survive as they have a respiratory system that relies on oxygen in the environment. Without oxygen, leeches would not be able to obtain the necessary energy for their survival.
Back then people would take leeches and let them suck the blood out because they thought it would take the sickness out.
I would say no. They are actually quite helpful. If you think they are mean, stop and ask yourself if you have done something wrong.
I've never heard it used as an idiom, but it sounds as if you are comparing people who habitually take something from you to leeches and should avoid them because they would keep taking from you -- perhaps energy or money.
People in a community are helpful, and are team workers.
I think it is the director, because helpful opinions would improve the play. Next time, you schouldn't let other people answer it for you.
