Detailed explanation-1: -Extinction occurs when species are diminished because of environmental forces (habitat fragmentation, global change, natural disaster, overexploitation of species for human use) or because of evolutionary changes in their members (genetic inbreeding, poor reproduction, decline in population numbers).
Detailed explanation-2: -As species go extinct, they are taken out of the food chain. Animals that ate the newly-extinct species have to find new food sources or starve. This can damage the populations of other plants or animals. Furthermore, if a predator goes extinct, its prey’s population can proliferate, unbalancing local ecosystems.
Detailed explanation-3: -Extinction is the death of all members of a species of plants, animals, or other organisms. One of the most dramatic examples of a modern extinction is the passenger pigeon.
Detailed explanation-4: -Extinction occurs when all members of a species are dead. This moment is typically marked by the death of the last individual of a species. There have been a series of mass extinctions in Earth’s history.
Detailed explanation-5: -Extinctions happen when a species dies out from cataclysmic events, evolutionary problems, or human interference. The truth is, scientists don’t know how many species of plants, animals, fungi, and bacteria exist on Earth.
