How are deserts and tundras similar?

Deserts and tundras are similar in that they are both extreme environments that support a limited and specialized range of plant and animal life. Both environments are characterized by low precipitation and harsh climatic conditions, with deserts being hot and dry while tundras are cold and snowy. They also typically have thin and fragile soil that is not suitable for agriculture or other forms of human habitation. Despite these challenges, both deserts and tundras are home to unique and highly adapted plant and animal species that have evolved to survive in these harsh environments.
