1. SEPTEMBER 19, 2013 List as many limiting factors that you can think of. Remember your Yoo Hoo Caribou graph is due tomorrow. Short TEST tomorrow over biotic and abiotic factors, limiting factors and carrying capacity.

3. Density Dependent Density Independent LIMITING FACTORS

4. DENSITY INDEPENDENT Natural Disasters Temperature Sunlight Human Activities Physical Characteristics Behaviors WHICH ONES ARE BIOTIC AND WHICH ARE ABIOTIC?

5. DENSITY INDEPENDENT Competition Predation Disease Parasitism Crowding WHICH ONES ARE BIOTIC AND WHICH ARE ABIOTIC?

6. BIODIVERSITY The number of different species of plants and animals in an area.

7. BIODIVERSITY THE GREATER THE VARIETY OF SPECIES, THE HEALTHIER THE BIOSPHERE IS!!

8. WHY BIODIVERSITY LEADS TO A MORE SUSTAINABLE ECOSYSTEM Sustainability is the ability to maintain something over a long period of time. More Species =More Links in the Food Chain More Plants = More Food for other animals (oxygen too) More Genes = Better Chance for Survival thru Adaptation Variety of Ecosystems = More Habitat for different Species

9. ENVIRONMENTAL CHANGES 1. How do changes in environmental conditions affect the survival of individual organisms and entire species? 2. How do populations respond to long-term environmental changes? 3. How do populations respond to short-term environmental changes? 4. How does human activity affect natural systems?
