2.4.3—Biome distribution determinants question 1
Table:Climate data for Norilsk and Novosibirsk within the tundra and taiga biome respectively
Table: Climate data for Norilsk and Novosibirsk within the tundra and taiga biome respectively climate comparison
• Norilsk (tundra): colder annual temperatures and fewer sunshine hours, especially during the growing season.
• Novosibirsk (taiga): warmer temperatures and generally more sunshine hours during the growing season.
• Precipitation is broadly comparable, so temperature and sunshine are the relevant contrasts for primary productivity.
With reference to Table: Climate data for Norilsk and Novosibirsk within the tundra and taiga biome respectively, suggest two reasons why primary productivity is greater in the taiga than in the tundra.
