Bubble lab
Homework: bubble lab conclusion

6. 2/24 Objective
• Discover how patterns of survivorship relate to the classic three types of survivorship curves.

7. Survivorship Curves-review
Type I:
High survival rate in young
Effective parenting
Overall low death rates
Type II:
Constant death rate
Limited parenting
Type III:
High death rate in young
No parenting
A lot of offspring because so many die
Once survive till a certain age, high survival rate

8. Match the curves to the populations
Type I
Type 2
Type 3
