a. true
b. false

True. Biomes are unique because average weather patterns in regions cause only certain types of animals to be adapted to live in those areas. Each region becomes uniquely filled with creatures that do not live anywhere else in the world. Go from region to region and each biome encountered will be found nowhere else in the world. There are several different types of biomes found in the world. Arctic tundra found across Alaska, Canada and Siberia is predominately cold with long cold winters and short summers that are not very hot. Deciduous forests located between the tropics and the arctic tundra have a warm and cold season. Deserts are very dry. Depending on the geographical location, they can be either hot or cold. Tropical rain forests have mostly a constant warm moist and because of this, most of the worlds biodiversity can be found here. Each biome is unique and found nowhere else on earth.
