Is there a difference between world vegetation regions and biomes?

Question

I saw a map of world vegetation regions, and it was very similar to biomes eg. tundra, savannah, rainforest etc.

Answer 1

Biomes are usually based on climate and geography but are similar in terms of ecology (vegetation, animals, etc.) so they are virtually the same thing in my opinion.

Answer 2

World vegetation regions and biomes are the same except that biomes place more emphasis on the inter-relatedness of the region known as an ecosystem.
