10. What are the importance to maintain biodiversity and the conservation of wildlife and their habitats? Suggest ways to protect the endangered species.

 

Biodiversity is a collective term encompassing species diversity, genetic diversity and ecosystem diversity.

The importance to maintain biodiversity is that all life forms are parts of the nature and each of them has a specific role in it. The loss of any one life form is irreversible. Every species helps scientists understand how life has evolved and how it will continue to evolve. The organisms in an ecosystem are interdependent. Each species forms important parts of food chains and plays a specific role in the ecosystem. For example, herbivores consume producers and transfer energy and essential nutrients to carnivores, and detritivores speed up the cycling processes of essential materials. This maintains a self-sufficient ecosystem. The diversity of ecosystems is biologically important. It is because organisms usually live in particular types of habitats, where the physical factors are suitable for them to survive. Biodiversity is an important part of our heritage, just like art, language and other cultural achievements. Humans have the role of stewardship of the natural world.
