I have cities, but no houses. I have mountains, but no trees. I have water, but no fish. What am I?

I'm full of holes yet I catch and hold, I'm woven tight but let things through, I work by trapping what tries to pass.

I’m a throw on the field, or stuck to the roof, I hum in your ear, or I’m a sticky goop. In music or sports, I’m known quite well, name me now come on, do tell!

feed me and it will give me life. but give me a drink and i will die. what am i?

I can serve others, but I cannot talk. You might see me in a cooking pot.
