The type of environment that is suitable for a certain species is its

habitat

Explanation:

A specie's habitat is the immediate environment suitable for the organism in which it lives and thrives. Each specie has specific adaptations which helps the organism to survive in its habitat. For instance, organisms that survive in arid regions have adaptive structures that minimizes water loss from the organism. The particular area inhabited by an organism within its habitat is the organism's ecological niche.

definition

                    entropy is a measure of the randomness or the extent of disorder of a chemical process.

                      enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

                        entropy is measured in joule per kelvin (jk⁻¹)   whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

                            entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

                              in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
