What is some devices to prevent species extinction?
The two devices that assist in the prevention of extinction are: game reserves and lodges (frequently with hunting) and zoos.
What are two examples of species that are success stories brought back from the brink of extinction?
Two examples of species that have been brought back from the brink of extinction are the American bison, which was once hunted to near extinction but has since recovered through conservation efforts, and the California condor, which was down to only 27 individuals but now has a population over 400 thanks to captive breeding programs.
Which two eras ended with mass extinction?
The Permian-Triassic extinction event, around 252 million years ago, marked the end of the Permian period and the beginning of the Triassic period. It is the most severe extinction event in Earth's history, wiping out approximately 95% of marine species and 70% of terrestrial vertebrate species. The Cretaceous-Paleogene extinction event, about 66 million years ago, ended the Cretaceous period and led to the extinction of the non-avian dinosaurs and about 75% of all plant and animal species.
Only two species of this mammal exist?
The two species are the Sumatran rhinoceros and the Javan rhinoceros. Both are critically endangered with declining populations due to habitat loss and poaching. Efforts are being made to protect and conserve these species in order to prevent their extinction.
What process accounts for species diversity?
Meiosis accounts for species diversity. Meiosis results in four rather than two daughter cells, each with a haploid set of chromosomes. Meiosis is responsible for producing gametes or sex cells.
What were the two main causes of the near extinction of the bison?
The two main causes of the near-extinction of the bison were 1. Habitat loss from ranching and farming, and 2. Commercial hunting.
What two factors contribute to extinction?
Mainly over hunting or people moving into the animals natural territory.the main factors contributing to extinction of a species would be:> over-hunting of the species by man> loss of habitat> climate change> a disease or virus spreading to and from other animals of the same species
What are two species thet are success stories brought back from the brink of extinction?
The bald eagle was one the species that were on the brink of extinction, and also the lynx bobcat. R.A.H.J.
Why does extinction endanger diversity?
Extinction is the permanent removal of a species which decreases bio-diversity. Bio-diversity is measured in two fashions # of species and # of members/species these two factors together make up a regions bio diversity, therefore with the removal of a species the regions bio-diversity decreases.
What is some devices to prevent species extinction?
The two devices that assist in the prevention of extinction are: game reserves and lodges (frequently with hunting) and zoos.
What killed the sloths?
Sloths are not extinct. There are four extant species, two of which are endangered and two which are in no apparent danger of extinction.
What are the two processes that determine the world's current biodiversity?
The two main processes that determine the world's current biodiversity are speciation, where new species arise through evolution, and extinction, where species die out due to various factors such as changes in the environment or competition with other species. These two processes continuously shape the diversity of life on Earth.

What are two main causes for animal loss in Africa?
I believe the two main causes are loss of habitat and hunting.
