An asteroid from space, and Gradualevents
For all mass extinctions (except the Cretaceous/Paleogene extinction) two probable causes are volcanic eruptions and ocean anoxia.
Mass and age.
There are several things that cause rainfall fluctuations. Two things that will cause rainfall to vary is the location and temperature.

An asteroid from space, and Gradualevents
For all mass extinctions (except the Cretaceous/Paleogene extinction) two probable causes are volcanic eruptions and ocean anoxia.
Most extinctions occur as background extinctions because they are longer time periods unlike the shorter mass extinctions which there were only two in the Paleozoic era, the Ordovician mass extinction, and the Permian/Triassic extinction in which 95% of all marine animals became extinct
climate change and asteroid impact
Two probable causes of mass extinctions are volcanic activity and asteroid impacts. Massive volcanic eruptions can release large amounts of ash and gases, leading to climate changes and disrupting ecosystems. Similarly, asteroid impacts can cause immediate destruction and trigger long-term environmental shifts, such as blocking sunlight and altering temperatures, resulting in the collapse of food chains. Both phenomena have been linked to significant biodiversity loss in Earth's history.
Two things that have mass are an apple and a rock.
Mass extinctions--at least two--one at the end of the Permian, and one at the end of the Cretaceous, with numerous other less severe events. As far as the extinction of individual species, that list would cover millions of extinct organisms.
Mass determines two things: gravitational attraction, and inertia.
The gravitational force between objects can be caused by their mass and the distance between them. The greater the mass of the objects and the shorter the distance between them, the stronger the gravitational force will be.
A low birth rate and environmental hazards are two things that can cause a population to decrease.
