3. Types of interactions between species
Mutualism  

4. Types of interactions between species
Commensalism  

5. Types of interactions between species
Parasitism  

7. Types of interactions between species
Predator/Prey

8. Predator & Prey Populations

9. Population growth
Carrying Capacity – The maximum number of organisms an ecosystem can support.
Limiting Factor – something that limits the carrying capacity of an environment.

10. Things that cause changes in a population
Birth
Death
Immigration
Emigration

11. Density-Dependent Factors
Becomes a bigger problem the closer to carrying capacity the population is.
Food
Competition
Parasites
Disease
Crowding/Stress/Violence

12. Density-inDependent Factors
Is a problem no matter what size the population is.
Temperature changes
Natural disasters
Polluted environments
Habitat destruction

13. Types of population growth:
Exponential growth
Logistic growth

14. Keystone species

17. Human Population Growth

21. 575 liters = 152 gallons

22. Urban Sprawl Poorly planned spreading of human development.
Causes habitat destruction, deforestation, pollution & loss of biodiversity
Solutions:
Establish growth boundaries (build up/fill in)
Mix residential, commercial, and work areas to reduce car usage.
Add more greenery
Add heading Invasive Species
