This document discusses different types of biodiversity including gene diversity, species diversity, and ecosystem diversity. Gene diversity refers to genetic variations within a species that can occur naturally or artificially. Species diversity is the difference between species that inhabit a particular habitat. Ecosystem diversity involves interactions between environmental conditions and biotic factors. Examples are provided of endangered species in Java that are threatened due to factors such as habitat loss, climate change, and low reproduction rates. Methods of protecting endangered species include conservation and cloning.

1. BIODIVERSITY

2. GENE DIVERSITY
• Gene diversity is the variation of genetic
differences or arrangements of a species.
• Gene diversity can occur naturally by
sexual reproduction or artificially by
hybridization done by human.
• Example: difference in color of puring,
difference in color of an Angora cat’s fur.

4. SPECIES DIVERSITY
• Species diversity is Difference between
species of living things that inhabit a
particular habitat.
• Species diversity is found on certain region
where group of organism of different
species live together.
• Example: difference of cat, lion, and tiger;
various of beans.

6. ECOSYSTEM DIVERSITY
• Ecosystem diversity is interactions between
different environmental conditions with the
group of biotic factors
• Example: rain forest, taiga, dessert, coral
reef, pond, river.

7. Rain forest ecosystem

8. Desert ecosystem

9. Coral reef ecosystem

10. Savanna ecosystem

11. ENDANGERED SPECIES
• Endangered species is species which has
lowest population in the world
• Example: java rhinoceros, java bull, orang
utan, java eagle, egret, estuary crocodile,
etc.

12. • Factor caused one named species
endangered:
1. Broken ecosystem caused Illegal logging,
pollution
2. Change of climate
3. Low viability
4. Low reproduction

13. Methods of protecting endangered species :
1. Conservation
2. Cloning
