Vaibhavi Apte. Biodiversity ???. Diversity = variety. Bio= living. Thus, variability among living organisms from all sources including inter alia, terrestrial, marine & other aquatic ecosystems and ecological complexes of which they are part of. .

Short for “biological diversity,” is the number of different species in a given area. Biodiversity hotspots. Why is it important? Why should we care? . Saving the Siberian Tiger. Siberian tigers are one of five remaining tiger subspecies.. In the early 20th century, hunting and habitat loss reduced the wild population to just 20–30 animals.. Conservation efforts have helped the wild population rebound to 450–500 today.. ANGGOTA KELOMPOK. SRI YUNIARTININGSIH (P2BA10009). YAYUK SUGIYARTI (P2BA10025). IHDA SYFAI (P2BA10010).
