Why do cactus live in dessert?

Answer 1

Cactus plants live by making changes within themselves to fit better with their extreme environments. For example, jungle equivalents of cactus plants don't grow on the tropical forest floor. Instead, they're epiphytic, which means that their roots are air born. They anchor themselves high up on tree trunks and branches. This is because jungle cactus plants face the opposite situation of desert cactus plants. They have access to enough moisture, in the hot humid tropics. But they'd be light deprived on the darker forest floor, where not enough sunlight filters down. So jungle cactus plants grow high up in the thick forest canopy, to be closer to what's in short supply: direct sunlight.
