Biological thermodynamics (Thermodynamics of biological systems) is a science that explains the nature and general laws of thermodynamic processes occurring in living organisms as nonequilibrium thermodynamic systems that convert the energy of the Sun and food into other types of energy. The nonequilibrium thermodynamic state of living ...
Rodents (primarily mice and rats) are the most common mammalian model systems used for studying gnotobiosis and are widely used to study human health relating to the gut and interactions between microorganisms and their host; however, recently there has been a rise in using gnotobiotic mice to study interactions between different microorganisms ...

In the U.S., the numbers of rats and mice used is estimated to be from 11 million [94] to between 20 and 100 million a year. [95] Other rodents commonly used are guinea pigs, hamsters, and gerbils. Mice are the most commonly used vertebrate species because of their size, low cost, ease of handling, and fast reproduction rate.
The term rat is also used in the names of other small mammals that are not true rats. Examples include the North American pack rats (aka wood rats [3]) and a number of species loosely called kangaroo rats. [3] Rats such as the bandicoot rat (Bandicota bengalensis) are murine rodents related to true rats but are not members of the genus Rattus ...
Dictyostelium discoideum is used in molecular biology and genetics, and is studied as an example of cell communication, differentiation, and programmed cell death. Laboratory mice, widely used in medical research. Among invertebrates, the fruit fly Drosophila melanogaster is famous as the subject of genetics experiments by Thomas Hunt Morgan ...
Secondary production is the use of energy stored in plants converted by consumers to their own biomass. Different ecosystems have different levels of consumers, all end with one top consumer. Most energy is stored in organic matter of plants, and as the consumers eat these plants they take up this energy.
Genetically modified mice have been the most common mammals used in biomedical research, as they are cheap and easy to manipulate. Examples include humanized mice created by xenotransplantation of human gene products, so as to be utilized as murine human-animal hybrids for gaining relevant insights in the in vivo context for understanding of ...
