Depends on the ecosystem,
The grizzly could survive another ecosystem, only if they can adapt to the changes or evolve. if they cannot evolve with the systematic changes : they will die off.
maybe because if there were other dolphins that went to their habitat then they mit not survive
it is called a grizzly stick.....as in....i got the grizzly stick...i know if i could hit once i could hit twice
fish
no
If the environment was very similar to Earth, yeah. Otherwise, no.
If it could catch it, yes, a Grizzly bear would eat a Pika.
Well it's not uncommon for a grizzly bear to prey on a small bison cow or a young calf, that's for sure. So yes, I guess you could say that a grizzly bear could kill a bison.
A grizzly bear could attack at any time. It's wild, it could seem friendly, but snap at any time.
All living things need the sun to survive in one way or another. All "natural" energy on Earth comes directly from the sun. So, to answer your question, plants could not survive if there was no sun.
Again, the grizzly bear, but it could die from the hot weather in africa.
Humans could not survive on another planet because they are all too hot, cold, dense, or far away.
Sure, they are in zoos all over the world. That is a different environment.
