A fossil is proof that an animal existed at one time, leaving evidence in rock. If that fossil does not appear in successive layers, there is no proof that the organism existed beyond its fossil record, and it is considered to have gone extinct.
Organisms such as dinosaurs, dodo birds, and woolly mammoths are extinct and will not reappear on Earth. However, it is possible that through cloning or other advanced technologies, we may be able to bring back some extinct species in the future.
Trilobites are extinct marine organisms that are often used to date rocks. They were widespread and diverse in the past, making them a useful tool for understanding the age of rock formations through biostratigraphy. Trilobites existed for over 270 million years before becoming extinct.
An extinct volcano must have not erupted in historical times (when history was first recorded). It takes many many years to distinguish an extinct volcano from a dormant one, and it is very difficult too. An example would be the Fourpeaked Mountain in Alaska, which prior to September 2006, is not believed to have erupted since earlier than 7994 BC! Mostly, it takes about 5,000 to 6,000 years for a dormant volcano to be considered extinct, except in rare cases. Another would be the hotspot theory. Whenever a volcano island moves away from the hotspot, the magma source is cut off, and the volcano is considered extinct. An example would the Hawaii Chain Islands.
No, the Common Blue butterfly is not extinct. It is a widespread species found throughout Europe and parts of Asia. However, its populations are declining due to habitat loss and climate change.
If all primary consumers became extinct, there would be a ripple effect through the food chain. This would lead to an increase in the population of primary producers, as there would be less pressure from herbivores. However, it could also disrupt the balance of the ecosystem and impact other organisms that depend on primary consumers for food.
It becomes extinct.
If an organism becomes extinct, its predators may struggle to find alternative food sources, leading to population declines or shifts in their feeding habits. This can have cascading effects on other species within the food web, potentially disrupting the balance and stability of the ecosystem.
When a species permanently disappears the species is said to be extinct.
Extinct.
extinct
Any living thing can become extinct.Extinct means that this organism no longer exists. This can happen to any type of living organism(or non-living organism, if you are talking about viruses). if you are refering to a human being the person has to die before that person is extinct
It depends on the organism.
It is an extinct organism.
When an organism becomes extinct, it can disrupt the ecosystem they were a part of, leading to cascading effects on other species and the environment. This loss of biodiversity can weaken the resilience of the ecosystem and impact its ability to provide essential services, such as food production and water purification, that are valuable to humans. Additionally, the extinction of a species can result in the loss of potential benefits that may have been derived from studying or using that organism for medicine, agriculture, or other purposes.
it depends on what organism
the organism has to reproduce otherwise the species will go extinct.
for something to be come pletle extinct.
