Population growth equation ecology
WebThe logistic equation of population growth has been applied to the growth of human populations as well as to the growth of many animal populations. In many modern text-books of ecology and population dynamics (Andrewartha and Birch [1954], Kendeigh [1961], Krebs [1972], McLaren [1971], Odum [1971], Slobodkin [1962], and Smith [1966]) Web1. Only three top-carnivores are supported in an ecosystem based on production of nearly 6 million plants. 2. Pyramid of biomass shows a sharp increase in biomass at higher trophic levels. 3. Pyramid of biomass is inverted if small standing crop of phytoplankton supports large standing crop of zooplankton. 4.
