The term that refers to a species facing dangers that will cause a significant reduction in its population is "endangered species." Endangered species are those at risk of becoming extinct due to factors such as habitat loss, pollution, overhunting, and climate change. These species are in critical need of conservation efforts to prevent their disappearance from the Earth.
Threatened species is another term closely related to endangered species, as it refers to species that are likely to become endangered if no action is taken to protect them. These species are also vulnerable and require conservation measures to ensure their survival.
On the other hand, domestic species are animals that have been selectively bred and managed by humans for various purposes like food, work, or companionship. They are not necessarily at risk of population reduction like endangered or threatened species.
Extinct species are those that no longer exist in the wild or anywhere on Earth. These species have completely disappeared, usually due to natural causes or human activities.
In summary:
1. Endangered species face dangers that will significantly reduce their population.
2. Threatened species are at risk of becoming endangered if conservation efforts are not implemented.
3. Domestic species are animals that have been selectively bred and managed by humans.
4. Extinct species no longer exist in the wild or anywhere on Earth.
