Which ones easier to survive in for a long period of time DESERT or RAINFOREST?

Rain forest. There is really some drinking water in various areas. There are many ways how to keep out of danger of a crocodile. First, running away in zig zag formation slows the crocodile down. Climbing trees works too, but it takes more time. A crocodile can run as fast a 400 mph for a very short time, so zig zag formation helps.
