What are the consequences of species extinction?
What are the consequences of extinction? If a species has a unique function in its ecosystem, its loss can prompt cascading effects through the food chain (a “trophic cascade”), impacting other species and the ecosystem itself.
What are extinct species give examples?
Here are examples of extinct animals:
- Dinosaurs.
- Woolly Mammoth.
- Dodo.
- West African Black Rhinocerous.
- Baiji White Dolphin.
- Tasmanian Tiger.
- Sabre-Toothed Tiger.
- Irish Elk.
How does extinction of species affect ecosystem?
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.
Why are some animals in danger of extinction?
Species become endangered for two main reasons: loss of habitat and loss of genetic variation. A loss of habitat can happen naturally. Human activity can also contribute to a loss of habitat. Development for housing, industry, and agriculture reduces the habitat of native organisms.

What are the effects of extinction of animals?
Effects of animal extinction When we lose the animals through extinction, we lose biodiversity. Biodiversity simply refers to the total number species as well as ecosystems in the earth’s surface or of a given place. It therefore reflects that when animals extinct, they reduces the variety of animals that were present in the earth’s surface.
Should we be concerned about species extinction?
Most of us don’t seem to be very cautious and concerned about the effects of species extinction. Species extinction threatens the human race more than any other species, damaged biodiversity can raise many problems such as deadly diseases, food shortages, and much more.
What is the relationship between biodiversity and extinction?
The biodiversity of an area is literally the number of species, both plant and animal, inhabiting the environment being examined. When a species is no longer found in a region, it is locally extinct. When it is no longer found anywhere, the species is considered extinct.
What is genus extinction and how does it lead to mass extinction?
Genus extinction could be as a result of limited geographic range thus can lead to mass extinction. In relation to this point, natural selection also play a very important role in that the weaker species is always get rid of and the stronger species is left to survive.
