About Desert Ecosystem
- A desert ecosystem is a natural system where living organisms (plants, animals, microbes) interact with non-living elements like soil, air, temperature, and water in very dry conditions.
- It is found in regions that receive very little rainfall (usually less than 50 cm per year) and experience extreme temperatures, either very hot or very cold.
- Deserts are considered the driest terrestrial ecosystems on Earth, which is why they have low biodiversity compared to other ecosystems like forests or grasslands.
- Despite harsh conditions, the plants and animals present are highly adapted to survive with limited water and extreme climate.
