Characteristics of different ecosystems found in a
local community
Features of natural, urban, agricultural,
aquacultural, freshwater and marine ecosystems
Resource: Biozone p.40-49
 Abiotic factors of a local ecosystem
 Impacts of temperature, pH, salinity, light, water
and atmospheric gases on the survival of organisms
living in that ecosystem
Resource: Biozone p.40-49
 Abiotic factors and their interaction with biotic
factors
 The sun as the original source of energy for
ecosystems
 Transfer of energy through food webs
Resource: Biozone p.52-60
 Role of producers, consumers and decomposers in
ecosystems
 Transfer of energy through ecosystems
 Food chains and food webs

differences in geographical and physical conditions
result in a wide variety of ecosystems

abiotic factors, including temperature, pH, salinity,
light, water and atmospheric gases, impact on the
survival of organisms within the environment

there is interaction between organisms, biological
communities and the abiotic environment in which
they live
the biotic components of an ecosystem transfer
and transform energy, originating primarily from
the sun, into biomass



producers, consumers and decomposers have a
role in the transfer of energy in an ecosystem
food chains and food webs show the feeding
relationships between organisms within a
community
1.5
Resource: Biozone p.61-64
 Pyramids of numbers and biomass
 Trophic levels and diminishing energy transfer

the amount of energy transferred between trophic
levels in food chains and food webs diminishes as
the trophic level increases
1.6
Resource: Biozone p.61-64
 Competition, predation, symbiosis, mutualism,
commensalism and parasitism

modes of interactions between species in
ecosystems include competition, predation and
symbiosis (mutualism, commensalism and
parasitism)
species interactions affect population densities and
are important in determining community structure
and composition
Resource: Biozone p.65-66

Central Ideas
Biogeochemical cycles as a natural circulation of
essential elements
The flow of elements from the abiotic to the biotic
components of the biosphere and back again
Examples of gaseous and sedimentary
biogeochemical cycles, including carbon, nitrogen,
water and phosphorus


Content
biotic components interact with abiotic
components to facilitate biogeochemical cycling
scientific knowledge can enable scientists to offer
valid explanations and make reliable predictions

Comparison of biodiversity between terrestrial and
aquatic ecosystems

biodiversity

biodiversity

Carrying capacity of an ecological population
Factors affecting carrying capacity
Natural selection, including: variation, changes in
the environment, selection pressures, survival and
change in characteristics
Behavioural, functional and structural adaptations
of endemic flora and fauna
Resource: Biozone p.133-134
 Behavioural, functional and structural adaptations
of invasive species (case study: cane toad)

YEAR 12 RETREAT
changes to abiotic and biotic factors, including
climatic events, impact on the carrying capacity of
ecosystems
scientific knowledge can be used to develop and
evaluate projected economic, social and
environmental impacts, and to design action for
sustainability
biodiversity includes the diversity of genetics,
species and ecosystems; biodiversity changes
naturally over time, and varies due to differences in
location
Task 4: Extended response (research and
validation) – Climatic events impacting on the
carrying capacity of a population [10%]
human interference is threatening biodiversity
through deterioration of ecosystems and
diminishing habitat areas
the use of scientific knowledge is influenced by
social, economic, cultural and ethical
considerations
the use of scientific knowledge may have beneficial
and/or harmful and/or unintended consequences
changes in ecosystems affect the survival of
organisms within the ecosystem; individual
variation assists survival, which over time results in
changes in characteristics of the species
Env. Deg. p11-12, 4043
variation in the form of suitable characteristics
assists survival of individuals
environmental changes may lead to selection of
advantageous biological characteristics within a
species
