Year 11 TAS Environmental Science practice questions
This public preview page identifies the planned Year 11 TAS Environmental Science demo route and links it to curriculum coverage while the reviewed sample question set is being completed.
Sample-question focus
The planned public sample is for Year 11 TAS Environmental Science practice and will open after the demo questions are reviewed.
Skills covered
Practice Earth systems, pollution, biodiversity, sustainability, food and water security, climate change, energy use, and scientific inquiry.
Exercise and test mode
The route is public now; the exercise and test preview will become available after the curated question set is ready.
Curriculum link
Compare this demo with the Tasmania Year 11-12 Environmental Science curriculum page to scan related topics, subtopics, and pathway coverage.
Sample TASC Year 11 Environmental Science questions
These sample questions are visible on the page before login. They show TASC Year 11 Environmental Science ecosystem structure, fieldwork data, water quality, resource use, energy flow, and sustainability decisions with diagrams, graphs, transects, and decision tables before opening the demo.
TASC Year 11Environmental ScienceMarine ecosystemshardenvironmental food web
1. A kelp-forest food web shows kelp eaten by sea urchins and sea urchins eaten by lobsters. If lobster numbers fall, what is the most direct risk?
Choices
Sea urchin grazing may increase.
Kelp becomes a predator.
Energy flows from urchins to sunlight.
All species must increase.
Explanation:
Fewer lobsters can reduce predation on sea urchins, allowing more grazing pressure on kelp.
TASC Year 11Environmental ScienceFieldworkhardfieldwork transect
2. A dune transect shows vegetation cover rising from 18% on the foredune to 64% behind the dune. Which statement matches the data?
Choices
Vegetation cover is greater behind the dune.
Vegetation cover is lower behind the dune.
No plants were measured.
The transect records only rainfall.
Explanation:
The graph shows a higher percentage cover behind the dune than on the foredune.
TASC Year 11Environmental ScienceWater qualityhardwater-quality graph
3. A nitrate graph shows 0.4 mg/L upstream and 1.6 mg/L below farmland runoff. What change is shown?
Choices
Nitrate concentration increased downstream.
Nitrate disappeared downstream.
The upstream value is higher.
Nitrate measures wind speed.
Explanation:
The downstream nitrate value is higher than the upstream value.
TASC Year 11Environmental ScienceResource usehardresource-flow diagram
4. A resource-flow diagram shows 75 kg of organic waste produced and 45 kg diverted to compost. What percentage was diverted?
Choices
60%
45%
30%
120%
Explanation:
45 / 75 x 100 = 60%.
TASC Year 11Environmental ScienceEnergy flowhardenergy-flow model
5. An energy model shows 7000 kJ in producers and 700 kJ in herbivores. What transfer percentage is represented?
Choices
10%
1%
70%
90%
Explanation:
The transfer is 700 / 7000 x 100 = 10%.
TASC Year 11Environmental ScienceSustainabilityhardsustainability matrix
6. A decision matrix scores a boardwalk 5 for erosion control, 4 for access and 2 for cost. Which criterion is weakest?
Choices
Cost
Erosion control
Access
All criteria tie
Explanation:
The lowest score is 2, assigned to cost.
For parents comparing TASC Year 11 Environmental Science support
TASC Year 11 Environmental Science practice should help students connect systems thinking to visible evidence: ecosystem structure, fieldwork data, water quality, resource use, energy flow, and sustainability decisions. These examples preview that visual reasoning before the no-login Environmental Science demo.

In progress
Year 11 TAS Environmental Science is available to purchase, and the public demo preview is still being prepared.
Students can use the purchased subject once subscribed; this anonymous preview will be opened after the curated public question set is ready.
Does this page include Year 11 TAS Environmental Science practice questions?
Not yet. The Year 11 TAS Environmental Science demo route is public, but the interactive sample questions will open after the reviewed public set is ready.
Can students try the demo without signing up?
No sign-up is required to view the preview status. The no-login interactive demo will be available after the sample set is completed.
How does this demo relate to curriculum coverage?
This demo is linked with the Tasmania Year 11-12 Environmental Science curriculum coverage page, where parents can compare the broader topic and pathway structure used for Skill Align practice.
