Section 3.5 - The Biodiversity Crisis Flashcards
Ecologists believe that the current extinction rate is high enough to match ____?
The great mass extinctions
What is a cost associated with human overpopulation and development ??
Accelerated extinction rate
The threat to species diversity is known as ?
Biodiversity crisis
What word? “Large scale dying out of a large percentage if all living organisms within an area over a short time”
Mass extinction
What word? “The current decline in genetic, species and ecosystem diversity that may represent a mass extinction”
Biodiversity crisis
What word? “A scientific method in which an idea about a mch Aniel is formulated and real-life data are then used to see if the data fit the model”
Modelling
Habitat destruction, competition from invasive species, illegal trade and pollution are all?
Threats
What is a major threat tot the survival of species?
Climate change
What word? “A system in which the sec of offspring is determined by incubation and temperature rather than genes”
Temperature sex determination
Impact of human population growth on diversity equation
Human overpopulation + development = accelerated extinction rate + biodiversity crisis
Current biodiversity threats are?? List 5
Habitat destruction Competition from invasive species Illegal trade Pollution Climate change
