Life is difficult to define, but there are characteristics of life that can be explored! We use these seven characteristics of life because life is hard to define. The more complex the system, the more characteristics it may have. Organisms that live in cold climates, such as the polar bear, have body structures that help them withstand low temperatures and conserve body heat.

These symptoms go away when you go back down to sea level. This process, change over time, is called evolution, and it is one of the processes that explain the diverse species seen in biology. In other words, think about how our bodies maintain a constant body temperature or how blood sugar levels are consistent. For example, a forest may include many pine trees. In other words, living processes can be viewed as a delay of the spontaneous or of the internal energy of biological towards more potential.

Other researchers reported related studies that life forms thrive inside rocks up to 580 m 1,900 ft; 0. This ability is fundamental to the process of and is determined by the organism's , diet, and external factors. These results led to the abandonment of scientific interest in vitalistic theories, although the belief lingered on in theories such as , which interprets diseases and sickness as caused by disturbances in a hypothetical vital force or life force.

Death Animal corpses, like this , are recycled by the , providing energy and nutrients for living creatures Death is the permanent termination of all vital functions or life processes in an organism or cell. Evolutionary biologists study the evolution of living things in everything from the microscopic world to ecosystems. Life can also be modeled as a network of inferior of regulatory mechanisms subordinated to a superior formed by the potential of expansion and reproduction. Multicellular organisms also reproduce in the strict sense of the term—that is, they make copies of themselves in the form of offspring—but they do so in a variety of ways, many involving complex organs and elaborate hormonal mechanisms.
