Program overview
Ecosystem dynamics is a Stage 6 Biology excursion using the long-nosed bandicoot as a real-world case study of habitat suitability and management. Students survey two bushland sites, collecting data on abiotic and biotic factors and human impacts, then analyse results to propose evidence-based management strategies that support threatened populations and Depth Study requirements.
Inquiry questions
- How do biotic and abiotic factors affect animal populations in natural areas?
- What fieldwork and analysis methodologies are needed for a valid and reliable habitat survey?
- How can human activities impact natural ecosystems and how should they be managed?
Fieldwork activities
Abiotic and biotic sampling
Students will conduct an ecological survey of two bushland sites to assess their suitability as habitats for the long-nosed bandicoot. They will use various fieldwork instruments and sampling methods to collect quantitative and qualitative data on biotic and abiotic factors relevant to the bandicoot’s ecological niche. They will record their data and observations using worksheets and digital technologies.
Human activities, impacts and management survey
Students find and record evidence of human activities at this site, identify environmental impacts, and develop management strategies to ensure the survival of the threatened long-nosed bandicoots.
Data interpretation, processing and analysis
Digital spreadsheets and graphic organisers will help students identify and discuss patterns and trends in their data. Staff will guide students to draw preliminary conclusions about their fieldwork inquiry questions.

Syllabus outcomes and content
Biology Stage 6 Syllabus (2017)
Outcomes
A student:
- develops and evaluates questions and hypotheses for scientific investigation BIO11/12-1
- designs and evaluates investigations in order to obtain primary and secondary data and information BIO11/12-2
- conducts investigations to collect valid and reliable primary and secondary data and information BIO11/12-3
- selects and processes appropriate qualitative and quantitative data and information using a range of appropriate media BIO11/12-4
- analyses and evaluates primary and secondary data and information BIO11/12-5
- analyses ecosystem dynamics and the interrelationships of organisms within the ecosystem BIO11-11
Module 4 Ecosystem Dynamics
Content
Students investigate and determine relationships between biotic and abiotic factors in an ecosystem, including:
- the impact of abiotic factors
- the impact of biotic factors, including predation, competition and symbiotic relationships
- the ecological niches occupied by species
- predicting consequences for populations in ecosystems due to predation, competition, symbiosis and disease
- measuring populations of organisms using sampling techniques
Students analyse evidence that present-day organisms have evolved from organisms in the past by examining and interpreting a range of secondary sources to evaluate processes, claims and conclusions relating to the evolution of organisms in Australia, for example:
- small mammals
Students investigate changes in past ecosystems that may inform our approach to the management of future ecosystems, including:
- the role of human-induced selection pressures on the extinction of species
- models that humans can use to predict future impacts on biodiversity
- the role of changing climate on ecosystems
Students investigate practices used to restore damaged ecosystems, country or place, for example:
- mining sites
- land degradation
