Question

Please help I am stressing.

Answer 1

"To take care of all it's needs". If a large creature's needs can not be met, it will die. Therefore, this would be the answer to your question.

Answer 2

Well if you look at the part before it that says there is not enough food then i would say the first option is the one to go to.  If you  are just looking at the phrase support a large creature then the last one would be a good answer.
