This essay explores how quantum physics can influence processes within biological systems. It looks at how biological systems have evolved to use and manipulate quantum effects. It focuses on decoherence, superposition (being in different places at the same time), and quantum entanglement (the connection between two or more particles despite distance). These effects are revealed through examples such as the workings of cells and their functioning, photosynthesis, where a balance between coherence and decoherence is maintained for energy transfer, and the way migratory birds navigate using quantum entanglement to sense the Earth's magnetic field, creating a kind of natural compass. Ultimately, the essay concludes that quantum physics has a very strong influence and presence in all biological systems, and that we can use such examples in some aspects of our lives.
