(c) Temperate coniferous forest are found in areas with cool winters, warm summers and abundant rainfall. Trees like spruce, pine and cedar grows here, but they have little undergrowth. They have a growing period of 50 to 100 days in a year. Rainfall is abundant but there is high range in spatial distribution of annual precipitation. Thus, option (a),(b) and (d) are correct. These areas have moderate temperature but experiences seasonal changes and considerable valuation. Temperate coniferous forest biome has high (and not low) variation in annual temperature. It ranges from an average of −40∘C in winters to 10∘C in summers.
