-TEMPERATURE influences the MOST
-Eology includes plants, animals, sunlight, soi, and other things

-will not compete for all resources
-if 2-3 organisms share a niche, then they must compete for resources
Niche:
-Function of an organism of an ecosystem
-Role of an organism in a community
-How it satisfies its need for food and protection
Competition:
- The number of niches in an ecosystem is limited in a certain area; two populations may try to occupy the same niche.
- They compete with one another.
- The one that us better adapted for the niche will win and will crowd out the other population; two organisms cannot occupy the same niche
