The previous two answers are correct, and for my contribution:
A biome is a large geographic area made up of ecosystems.
A terrestrial (land) biome is named after its climax vegetation,
which in turn is largely dependent upon the amount of annual rainfall (Basically, its climate).
Aquatic (water) biomes are much larger than terrestrial biomes because most of the earth is covered with water. Obviously the amount of rainfall doesn't matter here! The two kinds of water biomes are; fresh water & marine (salt/ocean). Most of the life on this planet is found in the water biomes,
and most of our atmospheric oxygen is produced here.
Water biomes are much more stable than land biomes (changes in temperature , for example).

The previous answer is correct, but in addition, it is useful to know what defines a biome versus an ecosystem. An ecosystem is defined by physical boundaries, such as a riparian zone along a river or the canopy in a forest. A biome is defined by climate. So for example, the Sonora Desert is a biome, as are the Great Plains, the tundra, the Amazon rain forest.

It is basically a lot of ecosystems put together. Examples include deserts, grasslands, tundra, tropical rain forest, etc.
