Answer:
In a desert ecosystem, which is characterized by its extreme aridity and harsh environmental conditions, there are still biotic factors, or living organisms, that have adapted to thrive in this challenging environment. Two examples of biotic factors in a desert ecosystem are:
1. **Desert Plants:** Desert plants, such as cacti, succulents, creosote bushes, and Joshua trees, are well-adapted to the arid conditions of the desert. They have evolved various mechanisms to conserve water, such as reduced leaf surfaces, water storage tissues, and deep root systems. These plants provide important sources of food and shelter for other desert organisms, including herbivores and some small mammals.
2. **Desert Animals:** Many animals have adapted to the desert environment. Examples of desert animals include reptiles like lizards and snakes, mammals like kangaroo rats, camels, and various species of birds, such as roadrunners and vultures. These animals have evolved physiological and behavioral adaptations to cope with limited water availability and extreme temperature fluctuations in the desert. Some are nocturnal to avoid the heat of the day, while others have specialized mechanisms for conserving water.
These biotic factors interact with each other and with the abiotic factors (non-living components) of the desert ecosystem, such as temperature, sunlight, and soil composition, to form a complex web of life in a seemingly inhospitable environment.
