These animals are threatened with extinction due to two main reasons, namely habitat loss and genetic diversity loss, and the following is an explanation of each of them:[2]

Habitat loss Which may occur naturally, for example, the dinosaurs lost their habitat nearly 65 million years ago, as the hot and dry climate changed very quickly as a result of an asteroid collision with the planet, and then the impact of the asteroid debris on the atmosphere, which led to a reduction The amount of heat and light that reaches the surface of the earth, and during this, dinosaurs are no longer able to adapt and coexist with their new, colder habitat than they used to, and thus dinosaurs have become endangered, and with the passage of time they have already become extinct.

loss of genetic diversity This is due to inbreeding, which means reproduction between close family members, and often what happens in groups of animals that tend to marry inbreeding with very little genetic diversity, and this is because new genetic genes are not presented to animals, and thus spreads among those groups Innate deadly disease, as Fungal species do not have the genetic variation that helps them develop resistance to disease, resulting in fewer offspring of fungal groups surviving until they grow and mature
