Kd = (concentration in one solvent) / (concentration in other solvent)
Because the solute is equally soluble in both, concentration in water = concentration in hexane. Therefore:
Kd = 1
Answer: A food chain describes how energy and nutrients move through an ecosystem. At the basic level there are plants that produce the energy, then it moves up to higher-level organisms like herbivores. ... In the food chain, energy is transferred from one living organism through another in the form of food. In ecology, a food chain is a series of organisms that eat one another so that energy and nutrients flow from one to the next. For example, if you had a hamburger for lunch, you might be part of a food chain that looks like this: grass rightarrow→right arrow cow rightarrow→right arrow human.
