Detailed explanation-1: -Reproduction is essential for the survival of a species beyond the life span of the existing members of that species. If members of a species are not reproducing, then once those members die out, the species will no longer exist. Eventually, the species will become extinct.
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: -There are three primary anthropogenic processes that lead to species endangerment and extinction-overharvesting; the introduction of nonnative species, including the spread of disease; and habitat destruction. For most endangered species in the United States today, the most serious threat is habitat destruction.
Detailed explanation-4: -Ecological importance Each species that is lost triggers the loss of other species within its ecosystem. Humans depend on healthy ecosystems to purify our environment. Without healthy forests, grasslands, rivers, oceans and other ecosystems, we will not have clean air, water, or land.
Detailed explanation-5: -Extinction happens when environmental factors or evolutionary problems cause a species to die out. The disappearance of species from Earth is ongoing, and rates have varied over time. A quarter of mammals is at risk of extinction, according to IUCN Red List estimates. To some extent, extinction is natural.
