This is absolutely false.
There is a wide diversity of life teaming around hydrothermal vents. These communities include primary producer organisms, but instead of obtaining energy from the sun, these bacteria use a process called chemosynthesis to convert minerals and other chemicals in the water into energy. These bacteria support a wide range of other animal species, including giant tube worms, deep sea mussels, serpulid or “feather duster” worms, and vent crabs, the apex predator of the vent community.
I thought it was savannah but grasslands could be it too.
The answer to #2 Is a..biota is the life of "a" plant, or animal (etc.) of the particular region/habitat, etc.
A mutation could do that.
