Ch 2: The Chemical Context of Life
The Chemical Context of Life
The Chemical Context of Life. Matter consists of chemical elements in pure form and in combinations called compounds Organisms are composed of matter.
Matter ◦ Organisms are composed of matter ◦ Matter is anything that takes up space and has mass ◦ Matter is made up of elements.
Essential idea: Living organisms control their composition by a complex web of chemical reactions.

Biology is a multidisciplinary science Living organisms are subject to basic laws of physics and chemistry One example is the use of formic acid by ants.
Concept 2.1: Matter consists of chemical elements in pure form and in combinations called compounds Organisms are composed of matter Matter is anything.
