Why do the leaves of deciduous trees in the temperate forest biome fall to the ground during winter?

• The tree has finished its life cycle.

• The tree cannot survive well in this biome.

• The tree has stopped absorbing water.

• The tree is not producing food at this time.

Events have causes, sometimes simple, sometimes multifaceted. Deciphering causal relationships, and the mechanisms by which they are mediated, is a major activity of science and engineering.
