Chapter 10Very briefly…
Objectives
Students will be able to:• Name the 6 most commonly found elements in all living
things.• Explain why carbon is essential to life
LEFT Question 1
Recall what were the 6 most common elements in ALL
living things?
Left - CHONPS
C = Carbon
H = Hydrogen
O = Oxygen
N = Nitrogen
P = Phosphorus
S = Sulfur
LEFT Question 2
Where do we get the elements we need?
CHONPS – you are what you eat• Where do we get these elements from?
• from our ENVIRONMENT!
• We eat a variety of foods that provide us with different nutrients and elements
• how else can we get these besides eating? • Breathing! Nitrogen (78%) and Oxygen (21%) are in the air.
