The 2nd law of thermodynamics states that the entropy, or disorder, of a closed system will always increase over time. This means that things tend to become more random and disorganized over time. However, living organisms are able to create and maintain complex structures and processes, which seems to defy this law.
No, the 2nd law of thermodynamics is still applicable to living organisms. However, living systems are able to decrease their own entropy by using energy from their surroundings and converting it into useful work. In other words, they are able to create order and complexity within themselves, but the overall entropy of the universe still increases.
One example is photosynthesis, where plants use energy from the sun to create complex molecules such as glucose. Another example is the process of metabolism, where living organisms break down and convert molecules into energy for their own use.
The 2nd law of thermodynamics applies to all systems, both living and non-living. It is a fundamental law of nature that governs the behavior of energy. In non-living systems, the law can be seen through processes such as heat transfer, chemical reactions, and diffusion.
No, life cannot exist in a completely isolated system as it would not have access to any external sources of energy. The ability of living organisms to decrease their own entropy relies on the input of external energy, which is not possible in a closed system.
