Living organisms are composed of matter, which is anything that occupies space and has mass (weight) – matter is composed of chemical elements – element — a substance that cannot be broken down to other substance – there are 92 elements in nature — only a few exist in a pure state – life requires 25 essential.

For example, only carbon makes alcohols that can make a series of phosphate esters, and again, these are extremely critical for life if you can't make something like atp, how do you transfer chemical energy so, basically, carbon is essential of course, so is nitrogen, hydrogen, oxygen, phosphate, and a number of other. From atoms to water in order to understand how any biological system works, from your body to something as complex as a forest, you need to have a basic understanding of chemistry basically, biology is the study of how living organisms process matter and energy we will cover energy in a later module, but for now, let's.
