Heinemann Biology Activity Manual Activity 1.3 A local ecosystem field study and report • Your task is to write up a report for your field study. • Fill in your information on the appropriate slides. You may need to copy some of the slides to include all your information: go to ‘Insert’ and choose ‘Insert duplicate slide’. • Make sure you link the starting slide for each topic back to the Index and that the topic is included in the Index. • You can insert or delete slides as needed. • Where possible, include digital or scanned photos of your ecosystem and your study. (This slide is an introduction only. When you have finished, go to ‘Edit’ and choose ‘Delete slide’.) A local ecosystem field study and report Presentation by: (insert your name here) (You can insert a different picture from file or a photo of your ecosystem. Delete this text box.) Name of ecosystem Index • Purpose • Conclusions • General area • Discussion: • Methods – abiotic factors • Results: – abiotic changes – abiotic – trophic interactions – biotic – habitats • Abundance & distribution – relationships • Impact of humans – future Purpose (Name the ecosystem you studied and explain what you were investigating.) (You can insert a different picture from file or a photo of your ecosystem. Delete this text box.) General area (Write a general description of the area, including abiotic and biotic factors.) Methods (Describe the methods used to conduct your study.) • … • … Results: abiotic factors Abiotic factor Air temperature at ground level at one metre Soil temperature Water temperature Light intensity Wind speed Soil pH Water pH Water turbidity Flow rate of water Dissolved oxygen content of water Measurement (Present a summary of your results.) Results: biotic factors Plant species • … • … Animal species • … • … (Prepare a list of the plant and animals species in the ecosystem.) Population abundance and distribution Plant species: (name) • The average size of the plant population was … Animal species: (name) • • (What is the abundance of the animal species in the area?) (How is the animal species distributed in the area?) Change in abundance and distribution • (Outline some factors that might account for the abundance and distribution of organisms in the ecosystem.) Change over time Plant species: (name) • (What changes occurred, or would occur, in the plant species over time of day, season, or time of year?) Animal species: (name) • (What changes occurred, or would occur, in the animal species over time of day, season or time of year?) Impact of humans Impacts humans have made on the ecosystem: • … • … • … How could the quality of the ecosystem be improved, maintained or preserved? • … • … • … Conclusion (Discuss how your results can be interpreted, their relevance, and any valid conclusions that can be drawn from them.) • … • … • … Discussion: abiotic factors (Include information about the abiotic factors and how these affect the distribution of organisms.) • … • … • … Discussion: abiotic changes (Suggest how the abiotic factors in this ecosystem are likely to change over a 24 hour period.) • … • … • … Discussion: trophic interactions (Include information about the trophic interactions of at least two plant and two animals species and how these interactions may affect distribution and abundance.) • … • … • … Discussion: habitats (Describe the habitats of four different kinds of living things in the ecosystem.) (Living thing 1) (Living thing 2) (Living thing 3) (Living thing 4) Discussion: relationships (Describe an example of each of the following kinds of relationships evident in the ecosystem.) • Predator–prey • Parasite–host (Explain how energy moves through the ecosystem.) Discussion: future (Include predictions about the future of the ecosystem you studied and any strategies that could be used to conserve and maintain it.) • … • … • …
