biodiversity
large region characterized by a specific type of climate and certain types of plant and animal communities.
biome
also known as coniferous forest. has trees with pines and leaves with a thick, waxy coating. average temp = 14 degrees C in summer, -10 degrees C in winter. Has finches, elk, porcupines, chickadees, etc.
taiga

organism that can’t synthesize its own food and is dependent on complex organic substances.
heterotroph
