What two things characterize a biome?
the climate and animals of the biome
Tundra is characterized by permafrost.
the decidous forest
temperature and amount of rainfall :D
Abiotic and biotic factors
Cold Winters, coniferous trees, and much snow
its plants or location
biomes are characterized by its general climate and the type of plant and animal species that live there. These characteristics depend on where the biome is located. For e…xample the tropical rain forest biome in the Brazil known as the Amzon Rain forest is called a rain forest because of its plants and animals, but the factor that makes it possible for the area to have such a moist and dense atmosphere is because it is near the equator.
Plants and animals.If there weren't any plants and animals in a biome the ecosystem wouldn't be able to stay in balance.If the ecosystem isn't in balance, then all of the plan…ts and animals would die off.
