if a species is declining then the species that eats that one has less food and will decline fast as well

Endangered, or critically endangered.
Are penquins getting endangered?
there are 17 species of penguin and they are all protected around the world but still the population of penguins is decreasing but most species of penguin are not endangered. According to the ESA the most vulnerable species of penguin is the Galapagos penguin. The African penguin is also being considered having the status of an endangered species. The southern rock hopper is named as threatened.This is a list of som of the other species of penguin.Gentoo penguin - Near threatenedMagellanic penguin - Near threatenedRockhopper penguin - Vulnerable (population declining)Macaroni penguin - Vulnerable (population declining)Fiordland crested penguin - Vulnerable (population declining)Snares Island penguin - Vulnerable (population small but currently stable)Royal penguin - (Vulnerable - population still recovering from being exploited in the past)Emperor penguin - Least concern (population stable)King penguin - Least concern (population stable or increasing)Adelie penguin - Least concern (population increasing in some regions, decreasing in others)Chinstrap penguin - Least concernFairy penguin - Least concernHope this helps xxx
Are island species vulnerable to extinction?
Actuallly, because of their isolated habitats, island species are more vulnerable to extinction. Introduced species,such as cats, mongoose, and others have led to the extinction of many birds especially, because of their inability to understand the tactics of the alien predator.
Who decides what animals are in danger?
It is not a who, but a what. It is the number of the population that determines the threat of extinction of an animal. There are five levels of threats. 1) Extinct- The animal is thought to be non-existent in the wild, and is maybe existent in captivity. 2) Critically Endangered- The animal is at high risk of extinction and has a quickly declining population or an extremely low population. 3) Endangered- At a considerable risk of extinction. The animal has a low population, a declining population, or a limited range. 4) Vulnerable- Animal at risk of extinction, but not on an immediate timescale. This is, in many cases, because of threatened habitats. 5) Lower Risk- The species is monitored, but not considered threatened. Sometimes, the animal will be classified as Lower Risk is too little data is available. I hope that this explanation has clearly answered your question!
What is a species which is vulnerable but not yet in immediate danger of extinction?
Jaguar, polar bear.
Is the okapi in danger of becoming extinct?
This animal is endangered, but not yet in imminent danger of extinction, with a population of at least 10,000, maybe 29,000 or more. The species is declining in some areas.
What term is used for species that are at serious risk of extinction?
Vulnerable, or Threatened. Both mean that events could endanger the species because of habitat change, or because the population level is low enough to where they could be endangered if the loss of some of the population occurs.
Are all penguins endangered?
Not all penguins are endangered yet.Under the Endangered Species Act (ESA), the penguin which is most at risk is the Galapagos penguin. It is listed as endangered, and this essentially means it is in danger of extinction within the foreseeable future throughmost of its range.Currently, the African penguin is also under consideration for being added to this endangered species list.The Southern Rockhopper is under consideration for being included on the threatened list.Under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), the Humboldtpenguin is also listed as endangered.Under the IUCN listing, the Erect Crested penguin and the Yellow eyed penguin are listed as endangered.The status of the other penguins is as follows:Gentoo penguin - Near threatenedMagellanic penguin - Near threatenedRockhopper penguin - Vulnerable (population declining)Macaroni penguin - Vulnerable (population declining)Fiordland crested penguin - Vulnerable (population declining)Snares Island penguin - Vulnerable (population small but currently stable)Royal penguin - (Vulnerable - population still recovering from being exploited in the past)Emperor penguin - Least concern (population stable)King penguin - Least concern (population stable or increasing)Adelie penguin - Least concern (population increasing in some regions, decreasing in others)Chinstrap penguin - Least concernFairy penguin - Least concern
Is a species that has few individuals at greater risk of extinction than a species that has a large population size?
Yes , species with very small populations are at the verge of extinction as compared to large population .
What make small populations vulnerable to extinction?
there are several factors that make small populations vulnerable. First off there are demographic factors. If a small population faces a forest fire, they are more susceptible to extinction opposed to a large, wide-spread population. you also have the lack of genetic availability. without genetic variation, a species can become prone to disease. there are many more, and I could go on.
What includes species extinction or endangerment?
Species endangerment is when the population is reduced below a point where it is sustainable. When the species is below this point, it can be reduced to the point to extinction.
Which manatees are endangered?
All three species of manatee are listed by the World Conservation Union as vulnerable to extinction.
