SUSTAINABLE ECOSYSTEMS AND THE INFLUENCE OF BIOTIC/ABIOTIC FACTORS

Sustainable Ecosystems and the Influence of Biotic/Abiotic Factors


Sustainability is based on a simple principle: Everything that is needed for survival and well-being depends, either directly or indirectly, on the natural environment. Sustainability creates and maintains the conditions under which humans and nature can exist in productive harmony, while also helping to fulfill the social and economic requirements of present and future generations.

In natural environments, the definition of sustainability is a property in which a process can be continued indefinitely without depleting the energy or material resources on which it depends. In essence, natural ecosystems are continually in a delicate balancing act to maintain equilibrium. With respect to population ecology, a sustainable population can be used to describe the dynamic relationship between a species and its environment. Numerous factors, both biotic and abiotic, can influence the success of a species in its natural environment over time. In this lab, you will learn about population ecology and its applications to better understand the influences affecting sustainable populations over time. You will also learn about prescribed fire and its application in environmental management to better understand fire dependent ecosystems in efforts to better maintain them sustainability.

This is an investigation of what is currently known about the question being asked. Use background information from credible references to write a short summary about concepts in the lab. List and cite references in APA style.


Hypothesis / Predicted Outcome:


An hypothesis is an “educated guess.” Based on what you have learned and written about in the Introduction, state what you expect to be the results of the lab procedures.


Methods:


Summarize the procedures that you used in the lab.


The Methods section should also state clearly how data (numbers) were collected during the lab; these will be reported in the Results/ Outcome section.


Results/Outcome:


Provide here any results / data that were generated doing the lab procedure.


Discussion/Analysis:


In this section, state clearly whether you obtained the expected results, and the outcome was as expected. Note: You can use answers to any multiple choice or essay questions you filled out in the lab to help you discuss the results and what you learned.


Provide references in APA format. This includes a reference list and in-text citations for references used in the Introduction section.


Give your paper a title and number and identify each section as specified above. Although the hypothesis will be a one sentence answer, the other sections will need to be paragraphs to adequately explain your experiment.


Submit your assignment as a MS Word document.
