Factors Within An Ecosystem.

Plant Stress Plant stress is defined as any change in environmental conditions that produce a less than ideal plant response.  Biotic  Abiotic.

What are Abiotic Factors?  Abiotic factors consist of the nonliving matter of the ecosystem.  These factors often limit the growth of organisms. 

Ecosystems. All the living and nonliving things that surround a living thing.

13.2 Biotic and Abiotic Factors Every ecosystem includes both living and nonliving factors.

Elements of Ecosystems  Biotic Factors: The living organisms in an ecosystem  plants, animals, fungi, etc.  Abiotic Factors: The non-living portions.

Pathology By: Tyler Hansberry. What is Pathology? Pathology is the study and diagnosis of disease through examination of organs, tissues, bodily fluids.

ECOLOGY The study of the environment and the interactions between living things and their biotic and abiotic surroundings.
