Organism Diversity in Ecosystems
1. Organism Diversity in Ecosystems 12/14/09 EQ: How do organisms diversify in an ecosystem? 12/13/2009 Bitsy Griffin Ecosystems 3
2. Getting the idea Ecosystems are home to many different organisms. Ecosystems host living and non-living parts. 12/13/2009 Bitsy Griffin Ecosystems 3
3. Getting the idea Ecosystems can host many different organisms because each organism uses the ecosystem differently. 12/13/2009 Bitsy Griffin Ecosystems 3
4. Populations & Communities Biotic organizations – Grouped into different levels: Populations Communities 12/13/2009 Bitsy Griffin Ecosystems 3
5. Population First level. Group of same species living in the same place. 12/13/2009 Bitsy Griffin Ecosystems 3
13. Habitats & Niches And many other things because each population has it’s own Habitat. 12/13/2009 Bitsy Griffin Ecosystems 3
14. Habitat The physical space used by a population. Habitat means Home Includes living and nonliving parts of ecosystem 12/13/2009 Bitsy Griffin Ecosystems 3
15. Habitat A black tailed deer’s habitat includes: 12/13/2009 Bitsy Griffin Ecosystems 3
24. Niche Both carnivorous Eat small mammals like mice & voles 12/13/2009 Bitsy Griffin Ecosystems 3
25. Niche BUT Owls are nocturnal Kestrels hunt in the day 12/13/2009 Bitsy Griffin Ecosystems 3
26. Niche They do not compete for food because they don’t hunt at the same time. They have different niches. 12/13/2009 Bitsy Griffin Ecosystems 3
27. Competition If two organisms occupy the same niche, They compete for resources 12/13/2009 Bitsy Griffin Ecosystems 3
28. Competition One organism usually becomes more efficient at finding & using resources They other may move or die out 12/13/2009 Bitsy Griffin Ecosystems 3
