investigate and determine relationships between biotic and abiotic factors in an ecosystem, including: (ACSBL019)

• the impact of abiotic factors (ACSBL021, ACSBL022, ACSBL025)

• the impact of biotic factors, including predation, competition and symbiotic relationships (ACSBL024)

• the ecological niches occupied by species (ACSBL023)

• predicting consequences for populations in ecosystems due to predation, competition, symbiosis and disease (ACSBL019, ACSBL020)

• measuring populations of organisms using sampling techniques (ACSBL003, ACSBL015)
