They will remain as black holes for a long, long time.
They get destroyed. Their matter becomes part of the black hole.
When they run out of fuel they collapse and become black holes.
Dead stars are not necessarily black holes. Dead stars can become white dwarfs, neutron stars, or black holes depending on their mass. Only the most massive dead stars can collapse further to become black holes if they exceed the Chandrasekhar limit, around 1.4 times the mass of the Sun.
Some do, some become "bright giants" instead.
The most massive stars become black holes.
No. Black holes are the remnants left behind when the very largest stars die.
They are called "black holes".
Stars can be sucked into black holes.
Yes. When the most massive stars die, their cores collapse to form black holes.

black holes are stars which collapsed under their own gravity.
False. Only the most massive stars will become black holes.
