Document Summary
Elements found in living and non-living matter are the same living cells obey the same fundamental laws of physics and chemistry as the abiotic (nonliving) world. Abiotic is known as nonbiological, often in reference to physical factors in the environment. Biotic is known as biological, often in reference to living components of the environment. Acquire energy from environment to maintain ordered state. Adjust structure, function, and behaviour in response to changes in external environment. Change and adapt to the environment over generations. The ability emerges from the interactions of all three of these as part of a metabolic process. The structural or functional complexity of living systems more than the sum of the parts, but it is fundamentally different. One of the tenets of the cell theory stated that cells arise only from the growth and division of pre- existing cells. But there must have been a time where this was no the case.
