A limiting factor is the one which limits the growth, abundance and distribution of the living beings in a particular region or ecosystem. The limiting factor can be non-living or living factor.
The 10 cm annual rainfall represents the limiting factor in the desert biome. The 10 cm annual rainfall will pose a challenge for the plants and animals growing and surviving in the desert biome. Some plants and animals survive due to adaptation others die, reduce in numbers or they may even extinct.
