1. Unit 5 Biomes, Ecosystems and Population Limiting Factors Part 4
Access Biology
Section 3

2. Life Levels and Organization
You have now learned about biosphere, biome and ecosystem. Next we are looking at community and population.

3. Groups of many different species of organisms interacting in a particular area (predator prey relationships)
Only the biotic factors that interact between different species of organisms
Community

5. Population
A group of organisms of one species that breed and live in the same place at the same time.

9. What do you think animals need to survive?
Before watching the video, brainstorm and decide what the 4 things could be? 1. 2. 3. 4.

11. We have looked at types of environments, now lets look more closely at how the populations interact and impact each other… View the video and identify examples of biotic and abiotic limiting factors.
Limiting Factors Click link to watch a short video on limiting factors.

12. What are some of the limiting factors?
can include competition, predation, parasitism, and/or disease.
Density-dependent factors
can include weather, natural disasters, seasonal cycles, human activities
Density-independent factors

13. The things animals need to survive are also impacted by the carrying capacity, how much is available in a population or community.
Carrying Capacity

14. Limiting Factors of Population Growth
There are factors which limit a population from getting too big. Click on this interactive site from Floridastudents.org to learn more…

15. Read an article about Limiting Factors, click link below.

17. Answer this question based on the video on previous slide.

18. Global Warming

19. What are Limiting Factors?
After viewing the video discuss these questions:
What is a biological carrying capacity?
What affects the capacity?
What are Limiting Factors?
This video goes with the lesson plan "To The Limit“ located at

20. Open up the links on each from the “To the Limit” lesson and discuss the impact on the population.
