• Example: rain forest, taiga, dessert, coral reef, pond, river.

Rain forest ecosystem

Desert ecosystem

Coral reef ecosystem

Savanna ecosystem

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.

• Factor caused one named species endangered:

1. Broken ecosystem caused Illegal logging, pollution

2. Change of climate

3. Low viability

4. Low reproduction

Methods of protecting endangered species :

1. Conservation

2. Cloning
