What is a biome? what are the six biomes?

a biome is a large naturally occurring community of flora (flowers) and fauna (animals) that live in a major habitat.

all biomes include:

tundra

taiga (also called boreal forest)

temperate deciduous forest

scrub forest (called chaparral in California)

grassland

desert

tropical rain forest

temperate rain forest

hope this helps :)

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
