EVERYDAY SCIENCE

Detailed explanation-1: -Species endangerment and extinction have three major anthropogenic causes-overhunting or overharvesting; introduction of nonnative species, including the spread of disease; and habitat degradation or loss.

Detailed explanation-2: -Explanation: The most important reason for the extinction of animals and plants is the loss of habitat and fragmentation. Habitat loss due to destruction, fragmentation, or degradation of habitat makes natural habitat incapable of supporting its native species.

Detailed explanation-3: -There are two main types of extinction: Mass extinction and background extinction. Mass extinction has only occurred five times in history. These are short and sudden phenomena caused by unnatural catastrophes such as asteroid impacts or volcanic eruptions. Over 50% of all species are wiped out at once.

Detailed explanation-4: -Demographic and genetic phenomena. Destruction of wild habitats. Introduction of invasive species. Climate change. Hunting and illegal trafficking.

Detailed explanation-5: -Asteroid Strikes. A meteor strike on the Yucatan peninsula in Mexico led to the disappearance of dinosaurs millions of years ago. Climate Change. Disease. Loss of habitat. Lack of Genetic Diversity. Better Adapted Competition. Pollution.
