They say decay and Meat eaters, or objects that eat other creatures is why.
Scientists do not believe that the extinction of the dinosaurs was the result of a great flood. There are still a number of competing theories about the extinction of the dinosaurs although it is clear that there was a large meteor impact in the Yucatan region, which played a role. It may also be that rising carbon dioxide levels and ocean acidity played a role as well. It may be that there were a number of contributing factors, rather than just one single cause. But scientists do not think that flooding was involved. Note that some dinosaurs were aquatic, and would not have been killed by flooding since they already lived in the water.
Only one thing: extinction.
One gradual change that can cause a mass extinction is climate change. If the Earth's temperature rises or falls significantly over time, it can disrupt ecosystems and lead to the extinction of many species that are unable to adapt quickly enough to the new conditions. This can result in a cascading effect on other species within the ecosystem, ultimately leading to a mass extinction event.
One type of catastrophic change that can cause a mass extinction is an asteroid impact. When a large asteroid collides with the Earth, it can release massive amounts of energy, cause widespread destruction, trigger tsunamis and wildfires, and create a global "impact winter" due to the release of dust and debris into the atmosphere. Such an event is believed to have caused the extinction of the dinosaurs 65 million years ago.
You are probably asking about the mass extinction at the Cretaceous-Mesozoic boundary, about 65 million years ago. We know that there was a major meteoric impact in the Yucatan peninsula at that time, which was at least partially involved in the mass extinction; some scientists believe that there were other contributing factors, but it remains a complicated and difficult issue to investigate.
Many scientists consider habitat loss and degradation to be the number one cause of extinction. This is primarily driven by human activities such as deforestation, urbanization, and agriculture, which destroy or fragment natural habitats. As ecosystems are altered or eliminated, the species that depend on them struggle to survive, leading to declines in biodiversity and increased extinction rates. Climate change and pollution also contribute to this crisis, but habitat loss remains the most significant factor.
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
Yes, hunting can cause extinction. Hunting destroys the animals life.
Human activity and pollution will probably be the greatest cause of elephant extinction.

Yes it can
sunlight
What_may_cause_a_lion_extinction
Yes.
poaching.
volcanic eruptions may cause mass extinctions or volcanic haze.a mass extinction is when a large number of species die out over a short period of geologic time and volcanic haze is when the gases of an eruption cause a haze and block out sunshine, causing a mass extinction.
