Abiotic Factors Affecting Organisms A scientific paper presented to Prof. Dagoc MSU-Iligan Institute of Technology College of Science and Mathematics In partial fulfillment of the requirements for The course in Bio107.2 (General Ecology Laboratory) By: Christian G. Lasala January 2014 ABIOTIC FACTORS AFFECTING ORGANISMS INTRODUCTION A human being cannot live alone. Neither can plants nor animals. All of them are dependent on one another, as well as on their surroundings including their environmental factors. Until the late 1960’s, a very little attention was paid to the relationship between organisms and their environment. Technology and scientific advances, however, brought about an awareness of the need to examine this relationbship more closely and improve it – to the advantage of both organism and environment which includes physical factors called abiotic factors. Abiotic factors are non-living chemical and physical factors or components in the biosphere, which affect ecosystems. The abiotic factors include sunlight, air, temperature, pressure, mountain slope, soil, rainfall, land drainage, and atmosphere. These environmental factors interact with one another. For example, soil can be affected by heavy rains or floods. Many abiotic factors can affect the lifestyle of an organism. These abiotic factors have subfactors, such as climatic and edaphic factors, that can have a huge impact on the survival, distribution, abundance and over-all ecology of the biotic units of the ecosystem. All these factors affect different organisms to different extents but without these environmental factors, organisms cannot exist. This study allows us to determine the variations of abiotic factors affecting organisms. It allows us to identify different organisms found in both sampling area. It allows us also to analyze how relevant these
