If trees need rain to live then why are they so good at keeping it of the gound around them ?
so whats the deal would some one pleeeeeeeeeeeeeeease answer this conundrum
Answers:
The leaves channel the water to the area at the edge of the leaves.this is where the most efficent water absorbing roots are, so they are getting more water by providing "shelter"..;
well the leaves absorb the water as well as the roots
With many trees, the roots will spread out beyond the canopy radius. I think the size of the canopy and root-system are harmoneous throughout a trees life. Some trees are instead deep-rooted, which means they can tap moisture rising from the water-table in the soil.
Deciduous trees don't have any/much leaf material from autumn to spring when it rains most.
Many plants can absorb moisture & nutrients through their leaves as well as roots. I believe those that can't are those with waxy leaves, but they are waxy so as they don't evaporate as much moisture in the first place.
like all plants trees can be over watered and this can cause the roots to rot and damage the tree, so the leaves keeping water off the ground around it is a self-defence mechanism. and as the roots can extend much further than the tree's canopy it can draw its water from a large area.
becuase not only do the leave absorb the rain, the roots also spread much further than the tree canopy itself, and they absorb the water they collect there, and yes, it is still a good place to hid from the rain.
The tree's roots absorb water from the ground. So it doesn't really need rain falling directly to it's foot.
the root system of trees are far larger than the canopy.
they didn't evolve to keep the water off the ground around them, that trait evolved as a way to increase surface area of cells that help photosynthisize and create energy from gathered sunlight.
in reality, most plants form mycorrhizal associations with fungi in the soil that have mycillia networks that extend the reach of plants roots even farther than their own large roots systems allow.
this is why sapplings in forests where tree canopies completely block direct sunlight are able to live rather than dying from lack of sunlight.
the mycorrhizal associations supply them with the nutrients that they are lacking by being shaded by larger trees.
The ends of the tree branches correspond with the location of the fibrous roots which absorb the water
