It is the fate of most living things eventually to go extinct. standard commonplace rate of extinction not associated with a mass extinction.
Is extinction the word you're looking for ?
the answer to the question is extinction
Scientists believe the Cretaceous-Paleogene extinction event, or the plants dying at the end of the Mesozoic Era, was caused by a massive asteroid/comet impact. The theory suggests that the impact had catastrophic effects on the environment, including an impact winter, which prevented the plants from carrying out photosynthesis.
Most scientists believe that the Cretaceous extinction event was caused by a 6 mile wide asteroid that impacted Earth at what is now the Yucatan Peninsula 65.5 million years ago. The impact would have thrown tremendous amounts of dust high into the atmosphere, which would have blocked the sun for months. Without sunlight, the plants would have died, and without the plants, so would any herbivorous animals. The carnivores would have then died, too. Another theory popular with scientists is that climate change was the cause of the extinction. Before the asteroid impact, a huge volcanic trap (a large lava flow) called the Deccan Traps had been erupting for about three million years. The amount of carbon dioxide it released into the atmosphere caused tremendous global climate change, and dramatically decreased the variety of dinosaur species. It is also very plausible that it was a combination of these two factors.
Dinosaur?
I believe it does. Scientists think that an asteroid wiped out the dinosaurs.
no, scientists have recently concluded that a asteroid killed them
Scientists are concerned about the ozone depletion. It is because this depletion can cause extinction of human race.
Scientists believe that changes in the Earth's climate cause extinction of trees;P

Most scientists do not believe in Biblical Creation, so there is no reason to tie it with the extinction of dinosaurs. However, Creationists often say that humans originally co-existed alongside dinosaurs until the Great Flood, when dinosaurs all drowned.
Bambiraptor lived in the Late Cretaceous period and i believe died out in the mass K-T extinction. this extinction would be where scientists believe that a meteor hit the Yucatan Peninsula.
Scientists find things out by doing experiments.
They say decay and Meat eaters, or objects that eat other creatures is why.
When we see that there are fossils found in a certain geological layer, which are evidence that a certain species existed at that time, and then in the next geological stratum we no longer find those fossils, and there is no evidence that the species which used to exist still exists, we infer that the species became extinct. If a whole lot of species become extinct at approximately the same time, we call that an extinction event, such as the KT extinction.
The extinction rate is much higher than it would be without humans, therefore most animals would have not gone extinct had it not been for human intervention.
