1. COMMUNITY ECOLOGY I pp

2. Species (organism)
Population
Community (interaction of different populations)
Ecosystem
Biosphere

3. SYMBIOSIS
Close interactions between two (populations) of organisms

5. Mutualism

8. Competition Niches overlap and resources are limited
a) Interspecific competition: two different
species use same food source
b) Intraspecific competition: competition
within the same species (population)
- very intense because they have identical
requirements

10. Niches overlap and resources are limited
Fundamental niche: set of resources a population is capable of using under ideal conditions
Realized niche: resources a population actually uses due to interspecific interactions

11. c) Competitive exclusion: one species presence causes other species to die, move, or switch to a new food source

12. d) Character displacement: divergence of characteristics (i. e
d) Character displacement: divergence of characteristics (i.e. beaks in finches)
e) Resource (niche) partitioning: using specific parts of the same resource (i.e. trees)
