The sophistication of contemporary instruments utilized in the research of statistical mechanics and box idea is frequently a disadvantage to the straightforward figuring out of recent very important present effects pronounced in journals. the most goal of this booklet is to introduce the reader to the tools of the fluctuation (field) conception of section transitions and important phenomena with a view to offer an exceptional resource for examine.

It is most probably important to have different weighting factors for organisms that are 34 Evolutionary Essays developed radically different and it is probably also important that the model focuses on the very problem that causes the structural changes, but whether the exergy contributions calculated are too high or too low is not important for a description of the structural changes. It is noteworthy that Coffaro et al. (1997), in his structural dynamic model of the Lagoon of Venice, did not calibrate the model describing the spatial pattern of various macrophytes species such as Ulva and Zostera, but used exergy-index optimization to estimate parameters determining the spatial distribution of these species.

The numbers used in these calculations are, however, still very uncertain. The other values in the table may, however, be changed similarly. 10 WHY LIVING SYSTEMS HAVE SUCH A HIGH LEVEL OF EXERGY? What is life? Most scientists would agree that life is 1. the ability to metabolite, that is to draw nutrients from the environment, and convert it into energy, useful biochemical compounds and excrete waste products 2. the ability to reproduce. These two abilities are rooted in an enormous amount of (useful) information, which is able to control the processes needed to metabolite and reproduce.
