Agriculture syllabus notes
calculate mean and standard deviation using trial data - correct answer-Mean on calculator
standard deviation on calculator.
calculate mean and standard deviation using trial data - correct answer-same
Climate - correct answer-Long term trends or temperature humidity rain seasons. This
matters so we know where we can best grow our plants.
collect and use meteorological data such as temperature, rainfall and evaporation (no
Answer) - correct answer-
conduct a simple plant trial using appropriate methodology - correct answer-Potatoes or the
cuttings.
construct a calendar of operations for an enterprise production cycle - correct answer-It is a
brief checklist of information that is time specific. It provides information to increase
efficiency. It is a monthly calendar with management tasks. It is constructed years in
advance.
Construct a flow chart of system (no answer) - correct answer-
construct a timeline of significant changes in land use practices since the arrival of
Europeans to Australia - correct answer-Did not cover this in detail. Ever since the arrival of
Europeans there was an increase in the use of fertilisers pesticides, herbicides etc and the
introduction of machinery such as the tractor.
describe agriculture as a system which is made up of inputs, outputs, boundaries,
subsystems, processes, interactions, feedback and monitoring - correct answer-Inputs things
entering a system. e.g. Cows, vaccines.
Outputs - exits a system e.g.g milk.
Boundaries - Distinguishes the system from the outside world. e.g. fence.
Subsystem, - System within a system. e.g. Soil , breeding parlour.
Processes (end with ing) - Something happening within a system e.g. fertilising.
Feedback - information coming into a system from the outside world. e.g. the milk company.
Monitoring - checks within a system. e.g. monitoring cow health
describe an important disease and pest for a selected farm animal - correct answer-Disease
- Tetanus. It occurs when dirt enters a cut or wound. It affects the nervous system and
causes muscles to tighten. It is also called lockjaw because it causes contractions in the jaw
and neck muscles.
Pest - Barber's pole worm. Eggs of the parasite a planted in animals faces when they hatch
the larvae are consumed by the host. The worm sucks the red blood cells of the animal
causing them to become anaemic. It creates a significant loss of appetite.
, describe how Indigenous Australians managed the land prior to the arrival of Europeans -
correct answer-Checkerboard burning - burning in some areas and leaving in others. Some
animals had green and burnt areas good for Kangaroo grazing. This also acts as an
ecological disturbance which is good for species to adjust and thrive in their environment.

describe the effect of demand and the role of consumer trends on farm production - correct
answer-Trends -
Decrease in meat consumption, increase in demand for sustainable milk, people consuming
healthy products and vegan.
If demand decreases - there is water and excess supply, lower prices can lead to changing
enterprises, value adding or out of business.
If demand increases - price increases, shortage in supply increase in externalities.
describe the factors affecting growth and development - correct answer-Growth - increase in
mass size and weight.
Development - Change in proportions of body caused by change in stage hormones.
Factors which effect - Hormones, nutrition, genetics, environment and temperature, disease,
original birth weight and sex.
Development usually starts slow but increases in speed. We develop bones first, then
muscle and then fat.
describe the functions of leaves, stems, roots, flowers, seeds and fruits - correct
answer-Leaves - Captures light for photosynthesis to produce food for the plant that can be
converted into energy.
Stems - Hold the plant up to receive sunlight. Transports water and nutrients.
Roots - keep the plant in the ground. Absorbs water and nutrients and transports.
Flowers - reproductive organ of the plant. Attracts pollinators to create fruits and disperse
seeds.
Seeds - Aid in germination and growth and distribution of flowers.
Fruits - Allow for the distribution of seeds.
