Why does an organism need energy and a constant supply of materials?
They are needed to replenish the ones that were used up in the process of existence.
In contrast to inorganic materials such as rocks and individual chemical compounds, "organisms" are entities that require external energy sources to grow or maintain their state of existence.
"Organisms" will die, or stop functioning, reverting to the fundamental chemical compositions of their structures and possibly becoming sources of energy for other organisms, unless they are continuously supplied with energy from a variety of sources.
"Entropy (disorder) is ALWAYS increasing" is a succinct way to describe the Second Law of Thermodynamics. Because living things are highly ordered assemblies of chemicals, they must constantly create disorder by utilizing energy and materials from other sources in order to create or maintain an area of higher order.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
