Clearly it contains a lot of water, and it gets nutrients from the soil. But it seems like plants continue to grow with no visible signs of soil degradation. Why doesn't the soil shrik in the pot?

Given that large broadleaf trees lose a lot of water on hot days, and some Redwoods can reach heights of more than 300 ft, it is obvious that enormous amounts of water must be moved. I don't think capillary action can account for this, and at the risk of sounding stupid, trees don't have hearts. Informed responses are appreciated.
