Chapter Learning Objectives Chapter 39: Population Growth and Regulation Define ecology and population o Ecology is the study of interrelationships between living things and their nonliving environment. o Population consists of all the members of a particular species that live within an ecosystem and can potentially interbreed. 39.1 How does population size change? Distinguish between biotic potential and environmental resistance o Biotic potential is the maximum rate at which the population could increase o Environmental resistance is the limitation for potential of growth by living and nonliving environments. It is imposed by the availability of food and space, competition with other organisms, and certain interactions among species, such as predation and parasitism, and natural events. Describe the variables involved in the exponential model of population growth o The growth rate equals the birth rate minus the death rate of a population.
