I have to do this survey for my science cl...?

if you are asking my favorite as a biome (as in which the best and worst example of a true biome) i would say the best is a lake/pond because it is the most contained with the least reliance of outside influence, least would be river because its ever changing always moving, but if your asking personal preference it would be a coral reef, very beautiful teaming with life, least would be a swamp because they tend to be more misunderstood
