You may be thinking that non-green plants do not have chlorophyll.....
But it's not true....
Non-green plants are not green because of the added pigments in it....
But it's not that it doesn't have chlorophyll....

They may also carry out nutrition through other means like....

-Saprophytic Nutrition
-Parasitic Nutrition

Every living being requires food and nutrition to survive. If they don't get that then they would die. Non-green plants are also living organisms.
They do not have chlorophyll to prepare their own food. But they may be 
saprophytes or parasites.For this reason only they may be growing in damp and warm places to get food and nutrition.

hope it helps.. :)
