* First law of thermodynamics: Energy may be transformed from one type into another but is never created or destroyed. | |||
* Second law of thermodynamics: No progress involving an energy transformation will spontaneously occur unless there is a degradation of the energy from a concentrated form into dispersed form. | |||
* One example regarding one single being: A being takes in chemical potential energy of food and converts a large part into heat to enable a small part of the energy to be reestablished as the chemical potential energy of new protoplasm<sup>1</sup>. | |||
* First, one has to consider the total amount of energy within an ecosystem and then think of the smaller amounts that flow through an organism. | |||
