Chapter 7 Study Guide

TermDefinition
Biodiversity Describes the variety of life across all levels of ecological organization.
Biodiversity hotspot Focuses attention on areas where the greatest number of species can be protected with the least effort.
Captive breeding Raising and breeding organisms in controlled conditions, such as zoos or aquariums.
Cloning Inserting DNa from an endangered species into a cultured egg cell; process involves implanting eggs into mothers of closely related species.
Ecosystem diversity Variety of habitats, ecosystems, and communities.
Ecotourism Environmentally responsible, tourism is a source of income for many nations.
Endangered species One that is at serious risk of extinction.
Endangered Species Act U.S. law that protects biodiversity, passed in 1973.
Extirpation Disappearance of a particular population from a given area but not of the entire species globally.
Genetic diversity Difference in DNA among individuals.
Habitat Fragmentation Patches of suitable habitat surrounded by unsuitable habitat.
Poaching Illegal capture or killing of an organization.
Species diversity Species diversity is a variety of species in a given area.
Threatened species Vulnerable species, one that is likely to become endangered soon throughout all or part of its range.
List and define 5 causes of biodiversity loss: 1: Invasive species 2:Pollution 3:Habitat change 4:Overharvesting 5:Human activity
What is the difference between a resistant ecosystem and a resilient ecosystem? Resistant- Change without losing function Resilient- Affected by change but bounce back & gain function
How can biodiversity benefit agriculture? Wild strays can be cross bred to transfer beneficial traits.
How can biodiversity benefit medicine? Organisms contain compounds that are useful for treating disease.
Why has ecotourism been suspended in the Galapagos Islands? Due to humans damaging the ecosystem too much.
Extinctions that occur one at a time, at a "normal" rate are referred to as what? Background extinction
When a large number of extinctions occur very quickly, the event is referred to as what? Mass extinction
Explain what happens during cloning. How could this help endangered Species? Nucleus from an egg cell is replaced with a somatic cell to produce a genetically identical copy of the parent. Can be used to produce multiple young's from an individual.
What is the greatest cause of biodiversity loss? Human activity
What are the characteristics of a stable ecosystem? 1: High level of biodiversity 2: Is resistant to environmental disturbances 3: Resilient & can recover quickly 4: Has a consistent energy flow 5: Has efficient nutrient cycling
