Which of the following limiting resources is competed for by organism in the desert?
Answer Details
In the desert, the resource that is most limited and competed for by organisms is water. This is because deserts are characterized by low and irregular rainfall, and water is crucial for survival. Organisms in the desert have evolved various adaptations to conserve water, such as having a thick waxy layer on leaves, storing water in their tissues, and being active at night when temperatures are cooler and moisture levels are higher. Without enough water, desert organisms would not be able to survive for long periods and would struggle to carry out essential functions like photosynthesis and regulating body temperature. While other resources such as light, temperature, oxygen, and carbon dioxide are also important, water is the most critical limiting factor in the desert ecosystem.
