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

Life Levels and Organization You have now learned about biosphere, biome and ecosystem. Next we are looking at community and population. Biosphere Biome Ecosystem Community Population invidual Life Levels and Organization

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

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

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. https://www.youtube.com/watch?v=pPw51fDTl68 Limiting Factors Click link to watch a short video on limiting factors.

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

The things animals need to survive are also impacted by the carrying capacity, how much is available in a population or community. https://www.youtube.com/watch?v=XV2-2Ym3IIc Carrying Capacity

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… http://www.floridastudents.org/PreviewResource/StudentResource/169134

Answer this question based on the video on previous slide.

Global Warming Read about how global warming is impacting the food supply for ecosystems, click link to link to story at NewsELA https://newsela.com/read/animals-dinner-time-global-warming/id/42471

What are Limiting Factors? After viewing the video discuss these questions: What is a biological carrying capacity? What affects the capacity? https://www.youtube.com/watch?feature=player_detailpage&v=QI2ixJeIxEU What are Limiting Factors? This video goes with the lesson plan "To The Limit“ located at http://www.cpalms.org/Public/PreviewResoaurceLesson/Preview/74297

Open up the links on each from the “To the Limit” lesson and discuss the impact on the population. http://www.cpalms.org/Uploads/resources/74297/10/71/docs/Limiting Factor Data MEA.docx http://www.cpalms.org/Public/PreviewResourceLesson/Preview/74297
