In fact, you may have heard that humans can go longer without food than they can without water. Without water all life would die. In addition to being an important part of cells, water is also used by plants to carry and distribute the nutrients they need to survive. As I Live and Breathe Ecosystems have lots of different living organisms that interact with each other. They are all important parts of an ecosystem.
Producers are the green plants.
