The organization of organisms has increased in complexity throughout time. In light of this trend, which of the following is true?

As organisms increase in complexity, the entropy in the surrounding universe correspondingly increases.
Each organism is considered a closed system, and therefore, increased organism complexity has no relationship to the laws of thermodynamics.
Organisms increase in complexity to maintain homeostasis with the decrease in entropy of the surrounding universe.
The increase in organism complexity is a function of evolution, not thermodynamics.
