Abiotic pollination

It occurs when pollination is mediated without the participation of other organisms. For illustration, anemophily is pollination by wind. This form of pollination is very common in grasses, most conifers, and a lot of deciduous trees. Hydrophily is pollination by water and occurs in aquatic plants which let go their seeds directly into the surrounding water. About 80% of all plant pollination is biotic, of the 20% of abiotically pollinated species, 98% is by wind and 2% by water.
