Document Summary
Organism perform best within a narrow range of conditions. Fundamental niche: is the optimum niche: realized niche is what you actually use to survive. Law of tolerance: the abundance and distribution of an organism can be determined by the deviation between location conditions (ex. Temperature) and the optimum set of conditions for a species. Abundance of organism is the highest at the optimum range. Why does temperature matter for survival: enzyme activity. Performance of organism is tied to the effect of temperature on enzyme activity. Psychrophilic: extremophilic organisms that are capable of growth and reprodu(cid:272)tio(cid:374) i(cid:374) lo(cid:449) te(cid:373)peratures, ra(cid:374)gi(cid:374)g fro(cid:373) (cid:1006)(cid:1004) c to +(cid:1005)(cid:1004) c. They are found in places that are permanently cold, such as the polar regions and the deep sea. Thermophilic: is an organism a type of extremophile that thrives at relatively high temperatures, between 41 and 122 c. What can organism do survive: die, migrate, acclimate, adapt.
