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.

What type of organism is no longer exists and will never again live on earth?

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.


What is the extinct marine organism that can be used to date rocks?

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.


How long is it before a volcano is 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.

What would happen if all of the primary consumers became extinct?

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.

What happens to the food web if an organism 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.

What differences does it make if an organism becomes extinct?

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.
