What could happen if a species’ food source declines over time?
The species must find another food source, move on, or it will begin to die off.
What are the most reactive groups?
#1,#2, #17
Extra: #16
The columns (vertical) on the Periodic Table of Elements. Each family of elements have the same number of valence electrons creating the same reactivity. There are 18 families.
