How much water, out of the total water evaporated from the oceans, is available to terrestrial ecosystem?

Solution (By Examveda Team)

Out of the total water evaporated from the oceans, 10% of water is available to terrestrial ecosystems.
The ocean plays a key role in this vital cycle of water. The ocean holds 97% of the total water on the planet; 78% of global precipitation occurs over the ocean, and it is the source of 86% of global evaporation.
Water controls the dynamics of terrestrial ecosystems directly, as a resource for the biota, and indirectly, as a driver for abiotic processes on the Earth's surface, in the atmosphere, and belowground.
