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

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