Answer:
In my opinion Alexander was Great, not only for his time, but in general in history.
Explanation:
Alexander the Great as history remembers him is one of the greatest generals and leaders not only of his time but in the history of humankind.
During his reign he created the largest Empire the world has seen until then. Not only that he created a vast empire, but he also managed to unify it through cultural means. He believed that the country he was ruling in should respect all differences and cultural diversity.
He was Great because his ideas were in front of his time, he was Great as a rule, he was great as a General.

The statement that is not true is: A healthy ecosystem can support an unlimited number of life forms.
Any ecosystem has its limits. No matter is a healthy, in perfect shape, and very large ecosystem, there's always a limit as to how much life forms can the ecosystem support. If the number of life forms surpasses the ability of the ecosystem to support them, than the ecosystem will crash, be destroyed, and experience a lot of changes, with the death of lot of life forms involved in the process as well.
There isn't such thing as an ecosystem that has the ability to support an infinite number of life forms, there's only ecosystems that are able to support limited number of life forms.
