Question

A sample of wood is found to contain 1/8 as much C-14 as is present in the wood of a living tree. What is the approximate age, in years, of this sample of wood?

Answer 1

An ecotone is a transition area between two biomes. It is where two communities meet and integrate. It may be narrow or wide, and it may be local (the zone between a field and forest) or regional (the transition between forest and grassland ecosystems).
