Thermodynamics in biology

Thermodynamics in biology studies how energy flows and transforms within living organisms. It explains processes like how cells convert nutrients into usable energy, how muscles generate movement, and how organisms maintain balance (homeostasis). Essentially, it shows that biological systems obey the same physical rules as everything else—energy is conserved, and some is lost as heat during transformations. This understanding helps explain how life sustains itself, grows, and functions efficiently within the constraints of energy conservation and entropy, which is the natural tendency toward disorder.
