The biome characterized by extreme temperatures and very little precipitation is known as a desert. Deserts can be classified into hot deserts, like the Sahara, and cold deserts, such as Antarctica. They typically receive less than 250 mm of rainfall annually, leading to unique adaptations in flora and fauna designed for water conservation. Plant species like cacti and succlulents store water, while animals exhibit behaviors such as nocturnal activity to avoid the heat. Deserts are crucial ecosystems that demonstrate the resilience of life under harsh conditions.
