Document Summary
This sugar molecule represents stored chemical energy that the producer can use: consumer = an organism that obtains energy and nutrients by feeding on another organism (e. g eating plants) This occurs when every female reproduces to her max potential and every offspring survives. This period of growth = exponential growth. Higher potential = high fecundity and reach reproductive maturity quickly. Higher the biotic potential, the faster the population of a given species will grow under ideal conditions. Exponential growth is typically seen when a species enter a new area, or there is an influx of new resources. Can"t last forever, growth rate will drop as population increase because resources start to become scarce: logistics growth = when population size increases, growth rate decreases. Reproductive strategies = how quickly a population can potentially increase reflecting the biology of the species (lifespan, maturity rateetc)
