Final answer:
The desert biome is characterized by low rainfall and dry conditions, with vegetation and animal life that have adapted to conserve water and endure high temperatures.
Step-by-step explanation:
The biome that is characterized by very little rainfall and dry conditions is the desert biome. This terrestrial biome is known for having particularly low precipitation, with rainfall typically less than 50 cm (about 20 inches) annually. Deserts are usually home to cacti, hardy shrubs, and can have high temperatures during the day. The vegetation and animal life in deserts have adapted to conserve water; plants may have deep roots and water-storing stems, while animals may exhibit nocturnal behavior to avoid daytime heat.
The biome that is characterized by very little rainfall and dry conditions is the desert. Deserts are generally dry ecosystems that receive very little rainfall. They are known for their high temperatures, cacti, hardy shrubs, and lack of perennial vegetation. Some adaptations that desert plants have to conserve water include deep roots, reduced foliage, and water-storing stems.
