In attempt to . explain the past in terms of present day processes. , Darwin went to local farmers and animal breeders and observed…. CHAPTER. Too Much of a Good Thing?. Elephant populations in southern Africa declined sharply due to hunting but have made overwhelming comebacks within nature reserves and parks.. Some worry that elephant overpopulation is causing a decline in local biodiversity and damage to farms and infrastructure.. A. Species overproduce offspring that may survive an environment.. B. There is little variation among members of a population.. C. Competition for resources, mates, and space among species leads to a struggle to survive.. Santa Monica Mountains National Recreation Area. Photo: Robert Taylor. Biomes of the World. Biomes are determined by the . climate. (temperature and precipitation). That, in turn, influences what . biota. Biomagnification. is the process by which matter becomes concentrated in living things in a food chain.. Moving up the Food Chain . DDT provides one example of the effects of . biomagnification. in an ecosystem. DDT is a chemical that was widely used to kill plant–eating insects. Some chemicals break down over time, but DDT does not. DDT collected in water and soil, was absorbed by living things, and moved up the food chain. The diagram shows how DDT became magnified in a wetland ecosystem. It entered through tiny organisms called zooplankton, which absorbed DDT from the water.. What is . Biodiversity. ?. It is the variety of earth’s species, the genes they contain, the ecosystems in which they live, and the ecosystems processes such as energy flow and nutrient cycling that sustain all life..
