Populations• A population is all of the organisms of one
species inhabiting a particular place

Population Size• Populations can increase or decrease in size
depending on different factors.

• What can cause a population to grow in size?

Population Growth Models
• Exponential vs. Logistic Growth

Exponential Growth
• J curve• Unlimited

Which Occurs More in Nature?
![Page 14: Do Now Collect materials from the front of the room Turn in Symbiosis worksheet (if you didn’t do it yesterday) Take your seat Remember: QUIZ ON Friday.](https://reader035.fdocuments.in/reader035/viewer/2022062519/5697bfc91a28abf838ca929d/html5/thumbnails/14.jpg)
Which Occurs More in Nature?
• Logistic Growth!
• Why?

Capacity• The maximum amount something can hold
• How does this relate to logistic growth of populations?
![Page 18: Do Now Collect materials from the front of the room Turn in Symbiosis worksheet (if you didn’t do it yesterday) Take your seat Remember: QUIZ ON Friday.](https://reader035.fdocuments.in/reader035/viewer/2022062519/5697bfc91a28abf838ca929d/html5/thumbnails/18.jpg)
Carrying Capacity• The population size an area can support
• Note: specific to the area and to the species!

What determines carrying capacity?

Limiting factors
• Density-dependent factors• Density-independent factors

Density Dependent
• Predation• Competition• Infectious
disease• Prey
availability

Exit Ticket
• Silently without notes!
• Why do populations have a carrying capacity?• (In other words why can’t populations
continue to grow forever?)
