Document Summary
Because we build rods, cities, industries ecological niche: niche = an organism"s use of resources and its functional role in a community, fundamental niche: optimal conditions. What the organism would do if it didn"t have competitors: realized niche: a subset of fundamental niche due to species interactions. Where is your greatest risk of dying: type i: more deaths at older ages, type ii: equal number of deaths at all ages, type iii: more deaths at young ages. Module 2 page 1: type iii: more deaths at young ages influence on reproductive strategies: influence on reproductive strategies: Populations may grow, shrink, or remain stable: natality = births, mortality = deaths, immigration = arrival from outside, emigration = departure to outside. Unregulated populations: steady growth rates cause exponential population growth, cannot be sustained indefinitely - because you will eventually begin to run out of resources, small population and ideal conditions.
