Explain why the distribution of biomes in the northern hemisphere is similar but not identical to the distribution of biomes in the southern hemisphere

The distribution of biomes is greatly influenced by the climatic conditions. The areas receiving more rainfall are lush green with variety of diverse species growing in that region while deserts have less vegetation.
The distribution of biomes in the Northern hemisphere is similar but not identical to the distribution of biomes in the Southern hemisphere. The Northern hemisphere is characterized by long and cold winters while summers are short. The Southern hemisphere is not as colder as Northern hemisphere except Antarctica. More oceans are present in the Southern hemisphere while Northern hemisphere has larger portions of the land. Also, the mountains in the Northern hemisphere has mountains and land that act as obstruction for the wind. Whereas, the wind blows unobstructed in Southern hemisphere. These are the reasons for not having identical biomes in both the regions.
