In Partial Fulfillment of the course Bio 107.2 General Ecology Laboratory December 2014 Introduction An ecosystem is an area in which there are living and non living things. Ecosystem has many interactions of the living and non living; living things in an ecosystem are called biotic factors including plants, animal, bacteria and more. Non living parts include sun, temperature, water, soil, humidity, and precipitation which are called abiotic factors. Biotic factors are all the living things or their materials that directly or indirectly affect an organism in its environment. This would include organisms, their presence, parts, interaction, and wastes. Factors such as parasitism, disease, and predation (one animal eating another) would also be classified as biotic factors (Buckley, James M. Jr., 1999-2003). Abiotic factors are those non-living physical and chemical factors which affect the ability of organisms to survive and reproduce. Abiotic factors vary in the environment and determining the types and numbers of organisms that exist in that environment. Factors which determine the types and numbers of organisms of a species in an ecosystem are called limiting factors. (Buckley, James M. Jr., 1999-2003). Through this study, the differences and variations in the physical environment of a sunny and shady area can be identified. The objectives of the study are the to acquaint the students with the different climatic and edaphic factors, to know the standard procedures used in measuring these factors, to determine variations in the physical environment in a small area consisting of grasses and trees, to identify organisms found in both areas, to analyze how individual organisms respond to
