Water relations refer to how organisms interact with water in their environment, which is crucial for their survival. This includes processes like absorption, transport, and excretion of water. Different species have adapted various strategies to manage their water needs, depending on their habitat, such as desert plants storing water or aquatic animals regulating their internal water balance. In ecosystems, water relations also influence plant growth and animal behavior. For instance, soil moisture affects how well plants can grow, while animals may migrate to find water sources. Understanding these relationships helps in managing natural resources and conserving biodiversity.
