Just the displacement of soil from the roots I think.Question: When a tree grows to weigh 10 tons, does the ground loose exactly 10 tons in an equal, pound for pound exchange?

Trees, like most plants, gets their energy from the sun and nutrients from the soil. Their entire mass is not derived from the soil. In fact, more than 90% of their mass comes from photosynthesis.Question: When a tree grows to weigh 10 tons, does the ground loose exactly 10 tons in an equal, pound for pound exchange?

I notice that the wood of trees is close to 60% carbon, and we are made of much carbon... would it be safe to say that the sun is responsible for the construction of new carbon matter to form on earth? Thus slightly increasing earths mass through the sun's rays via life..?
Carbon-based life - Wikipedia
Our forests are carbon reservoirs. They sequester huge volumes of carbon. At least until will burn them down to make new space for cows and subdivisions.Let's be more clear. 90% of the mass comes from the *air*. The carbon, in particular, is mostly from carbon dioxide in the air.

Carbon is indeed fairly unique in its binding properties, because it can assemble into massive molecules with a wide variety of other elements (though predominantly Hydrogen, Oxygen and Nitrogen, all of which are plentiful on Earth)....I wonder if it has something to do with carbon's readiness to become 3 dimensional, which makes it so unique compared to other molecules.

It seems so useful on a molecular level. But the potentiality of a third dimension of it seems mystical to me.

@Tambourine hits the nail on the head. The unique thing that makes carbon so suitable for biochemIstry is "catenation": the tendency for carbon to form long chains -C-C-C-C-C..........I wonder if it has something to do with carbon's readiness to become 3 dimensional, which makes it so unique compared to other molecules.

What does that mean?
It means that carbon (C) easily bonds to other atoms to create 3-dimensional shapes.

...There are an abundance of other elements, which don't do that, and end up looking like:

Because with h2o, you can never have a 3-dimensional snowflake, because the molecules are not 3-dimensional -they're pancake shaped, two-dimensional. But with 3-dimensional molecules, stacked on top of each other, we can have things like DNA and trees that can grow in every direction -not like flat pieces of paper.
Hydrocarbon - Three-dimensional structures
Um, look at ice. It is a three dimensional crystal. Those water molecules can turn in three dimensions and, in doing so, find better configurations than the two dimensional arrangements.
In fact, the angle between bonds in water is close to that between bonds in methane. The reason is that there are two *filled* orbitals in the oxygen of water. Those orbitals can still do hydrogen-bonding between molecules in a three dimensional structure.
And, don't forget nitrogen: ammonia is three dimensional. Silicon also forms complex three dimensional structures with oxygen. And the transition elements tend to form very complex three dimensional complexes.
I might suggest you take some chemistry classes.
