1 Ecology: We are all connected and interdependent Bonus #3 due 4/30/08

2 Species in a N. Am. forest

3 Ecological Interconnections

4 CB 54.2 Interconnections

5 http://youtube.com/watch?v=dA0qGlnc-30

6 CB 52.21 Predator-Prey interactions

7 CB 52.12 Carrying Capacity exponential growth stationary phase

8 CB 52.22 Human Population Growth

9 CB 52.12 What limits Carrying Capacity?… exponential growth stationary phase

10 Space …Availability of resources.

11 CB 54.2 Availability of resources and removal of waste limits carrying capacity

12 CB 54.11 Energy is lost in each consumer

13 CB 54.13 Less consumers than producers

14 CB 54.11 Energy is lost as it is consumed: where does it go?

15 CB 54.10 only a small percent of energy is stored in organism

16

17 Space …Availability of resources.

18 CB 54.17 Nitrogen cycle 80% in air

19 CB 5.16 Nitrogen as part of amino acids NNN

20 CB 54.17 Nitrogen cycle 80% in air

21 CB 50.19 Ecosystems on Earth: resources are not evenly distributed

22 CB 53.23 Number of bird species: Areas of higher and lower biodiversity reflect available resources

24 CB 55.15 Rainforest clear cutting

25 Human impacts: Pollution in Gulf of Mexico from Mississippi river

26 CB 54.14 Reducing consumption of resources can increase carrying capacity: Human impact as consumers

27 CB 54.17 Carbon cycle

28 CB 54.24 CO 2 levels in Hawaii and average global temp.

29 Effects of global climate change are already visible http://www.nationmaster.c om/graph/env_co2_emi- environment-co2- emissions 1914 2004

30 Polar bears need ice to hunt

31 Sea Ice 1979 2003

32 Without sea ice, polar bears will go extinct
