8. What happens when two different interacting species of organisms use the same niche?

9. Competitive Exclusion: Two interacting populations of species using the same niche will not maintain stable population sizes. Long term, one of two things will happen…..

10. 1. The species with the advantage will cause the other to become locally extinct.

12. 2. Species will change their behavior or adapt to fill another niche http://www.saburchill.com/IBbiology/chapters0 2/images/08060302.jpg

13. Fundamental Niche: the full niche that a species is capable of using without any competition Realized Niche: The actual niche that a species uses

15. Competitive exclusions causes the difference between fundamental and realized niches http://www.asdk12.org/staff/vanarsdale_mark/pages/mrva/marine/Marine_Eco logy_Images/Niche_L.jpg

16. What might be some consequences of introducing a new species of small insect eating bird into Santa Maria? What type of human activities might create more competitive exclusion and local extinction between organisms? Is this good?

17. And NUH is the letter I use to spell Nutches, Who live in small caves, known as Niches, for hutches. These Nutches have troubles, the biggest of which is The fact there are many more Nutches than Niches. Each Nutch in a Niche knows that some other Nutch Would like to move into his Niche very much. So each Nutch in a Niche has to watch that small Niche Or Nutches who haven’t got Niches will snitch. Dr. Seuss – On Beyond Zebra (1955)
