What is the world's largest biome?

Answer 1

It depends upon whom you ask. It could be "Ocean"/"Saltwater", "Taiga" or something else depending on how they are classified.

Depending on how one defines a biome, it can mean anything from an area of similar biodiversity to the majority of the world's surface covered by saltwater, which some refer to as "Ocean" and others as "Saltwater" (University of California press release).

Some define a biome as "similar biodiversity across continents," which suggests that it is a LAND surface area, and they would say that the Taiga biome covers more land than any other land biome. This is according to Wikipedia.

The Wikipedia article does a good job of illustrating the variety of definitions that exist for biomes.
