5.3 - Conserving Biodiversity Flashcards
what is a renewable resource?
Resources that are replaced by natural processes faster than they are consumed
what is a nonrenewable resource?
Resources that are found on Earth in limited amounts or those that are replaced by natural processes over extremely long periods of time
what is sustainable use?
using resources at a rate at which they can be replaced or recycled while preserving the long-term environmental health of the biosphere.
what are endemic species?
a species only found in one specific geographic location.
what are corridors/what do they do?
Connect smaller parcels of land, allowing organisms to move safely between them
Create a larger piece of land that can sustain a wider variety of species and a wider variety of genetic variation
Can also pass disease and infection between fragments and increase edge effects
how can biological communities recover from human made disasters?
when given the appropriate amount of time
what methods do ecologists use to speed up recovery time?
bioremediation and biological augmentation
what is bioremediation?
The use of living organisms, such as prokaryotes, fungi, or plants, to detoxify a polluted area
what is biological augmentation?
Adding natural predators to a degraded ecosystem
what are the two classes of natural resources?
renewable and nonrenewable
what are the two methods used to conserve biodiversity?
what are the two techniques used to restore biodiversity?
bioremediation and biological augmentation
