5 B. Ecosystem The living and the nonliving things in an area.

7 1. Water - all life processes depend on water.

8

9 2. Soil - determines the types of plants that can live in a certain location.

10

11 3. Sunlight - provides energy for all living things.

12

13 4. Temperature - determines the organisms that can live there.

14

15 5. Oxygen - most living things require it to live.
