Extinction rates vary and can sometimes be rapid, and some times slow. Extinction rates are affected by biotic, competition between species, hunting etc, and abiotic factors, volcano eruptions, weather etc.
Each year as many as 50,000 species of animals and plants become extinct due to deforestation and hunting. This causes the food chain to muddle up, and other animals die out. If one animal or plant becomes extinct, then the prey of the animal becomes overpopulated with nothing to eat them, and the predator dies off because it has nothing to feed on. It has a hge effect on other animals if one animal becomes extinct.
Some people say one animal goes extinct a day. So if this was correct 365/366 animals would go extinct every year. But this number has not been scientifically proven and is a very rough estimate. The real number is unknown as many species that become extinct are unknown to science.
It really all depends on the type of animal(for instance something that has less offspring may be more likely to become extinct first it also depends on were they live,the fish in the Gulf of Mexico have alot less of a chance of survival than a bear in a government owned forest)
100 different animals become extinct every year!
A species is extinct when the last individual has died.
Species become extinct when the species does not have any more resources to live on or when they stop mating and die out.

35,150 animals become extinct every year.
In the Amazon Rainforest alone, 1 species becomes extinct every 15 seconds!
Every single tree you can emagine! 157 species are extinct each year.
five or six species...
It changes and many different scientists have different opinions, since the total number of species (including bacteria) cannot be precisely determined. One estimate is that from 25 to 150 species of animals become extinct every day. Most if not all are microorganisms replaced by species with greater survivability.

Nobody really knows how many species a year are going extinct from human actions. Recent estimates for the extinction rate of animals by human action vary from 10,000 to 100,000.
There are about 240 different species of shrews, and more are discovered every year.
200000 billion
Under the Endangered Species Act of 1973 "the term 'endangered species' means any species which is in danger of extinction throughout all or a significant portion of its range other than a species of the Class Insecta determined by the Secretary to constitute a pest whose protection under the provisions of this Act would present an overwhelming and overriding risk to man. "A threatened species "means any species which is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range." In other words, an endangered species is a group of plants or animals that is in danger of becoming extinct. Many scientists say a species is endangered when its numbers are so low or its habitat so threatened that it will become extinct in 10 to 15 years unless conservation measures are used to save it. People who study wildlife think there are at least 10 million and possibly as many as 30 million species of plants and animals on Earth. They estimate that more than one-tenth of these species are endangered. That adds up to at least one million kinds of plants and animals that could become extinct by the year 2015. In recent years the rate of extinction has increased rapidly in many places . In the past 300 years, about 100 kinds of mammals have become extinct. Right now hundreds of birds, mammals, reptiles, amphibians, and fish are endangered, as well as more than 25,000 plants. The American Museum of Natural History in New York reports: "Three species become extinct every hour of every day. More than 30 species become extinct while you sleep at night. More than 20,000 species become extinct every year."
The Mississippi River has an unkown amount of species living in it because there are many found every year
No. The only state in which any species of horned toads are endangered is Texas, with the Texas horned toad.
