7. A Pond Ecosystem
Are all of these things living?
NO!! An ecosystem has many important parts that are living and non-living.
                                                               

8. A Pond Ecosystem Living Non-Living
Are all of these things living?
Living Non-Living
Fish Water
Plants Soil

9. The Nonliving Environment
Abiotic factors- the nonliving parts of an organism’s environment.
Examples include air, water, temperature, rocks and minerals, light, and soil.
Abiotic factors affect an organism’s life.

10. The Living Environment
Biotic factors- all the living (or once-living) organisms that inhabit an environment.
All organisms depend on others directly or indirectly for food, shelter, reproduction, or protection.

11. Biotic Factors The living parts of an ecosystem.
They include animals, plants, fungi, protists, and bacteria.

36. Objective: Importance of Abiotic Factors
Essential Question: What role do abiotic factors play in ecosystems?

37. What role do abiotic factors play in an ecosystem?

38. What role do abiotic factors play in an ecosystem?
Sun
*Provides Light, Heat, and Energy
*Without the sun: All biotic factors (all living things) would die

39. What role do abiotic factors play in an ecosystem?
Water
*Provides a place to live for many creatures, hydrates all biotic factors
*Without water: All biotic factors (all living things) would die

40. What role do abiotic factors play in an ecosystem?
Air
*Helps many biotic factors breathe
*Without air: Most biotic factors (most living things) would die

41. What role do abiotic factors play in an ecosystem?
Temperature
*Many creatures can only survive in certain temperatures
*Extreme temperature changes: Could kill many of the biotic factors

42. What role do abiotic factors play in an ecosystem?
Soil
*Provides a home, nutrients, support
*Without the soil: Plants would die and many biotic factors would be affected

43. What would happen to all the biotic factors if there were no abiotic factors?

44. What would happen to all the biotic factors if there were no abiotic factors?
All biotic factors would DIE without abiotic factors!!!!!!

45. What would happen to the biotic factors in this ecosystem if…
There was no sun
There was no water
There was no soil
There were no minerals
