Answer:
1. The biotic factors seen in the photo include various species of cacti, shrubs, and succulents.
2. The abiotic factors detected in the photo include light, temperature, soil, and water.
3. The biotic factors interact with abiotic factors in many ways. For example, cacti and other desert plants need light, water, and soil to survive, while their leaves and stems help to regulate temperature and prevent water loss. In addition, the presence of plants can alter the soil composition by adding organic matter and nitrogen, both of which are important for sustaining life in the desert.
