Aquaponics (the farming of fish in artificial pond-like environments) can be seen as sustainable because...
- A.
It is an additional income stream for struggling farmers.
- B.
It recycles nutrients which would otherwise go to waste.
- C.
Its prime purpose is to restock local streams.
- D.
It often involves the use of antibiotics to combat disease, ensuring healthy fish.
Correct Answer
B. It recycles nutrients which would otherwise go to waste.Explanation
Aquaponics is considered sustainable because it recycles nutrients that would otherwise go to waste. In this farming method, fish waste provides nutrients to plants, and the plants, in turn, filter the water for the fish. This closed-loop system minimizes the need for additional fertilizers and reduces water usage. By utilizing the waste produced by the fish, aquaponics maximizes resource efficiency and minimizes environmental impact. Additionally, this method allows for the production of both fish and crops, providing a more diverse and resilient income stream for farmers.Rate this question:

- B.
Research into how re-snagging of the river has affected cod numbers by assessing numbers where this has occurred.
- C.
Research anecdotes from local fishermen about how fish numbers and species have changed over time.
- D.
Assessing which bait Murray cod are least likely to bite on.
Correct Answer
D. Assessing which bait Murray cod are least likely to bite on.Explanation
A sustainability science project in fisheries management focuses on understanding and promoting the long-term viability of fish populations and their ecosystems. It involves researching the impact of various factors on fish populations, such as changes in their habitats, historical trends in population numbers, and local knowledge from fishermen. However, assessing which bait Murray cod are least likely to bite on is not directly related to sustainability or the management of fish populations. This information may be useful for recreational fishing purposes, but it does not contribute to the overall goal of sustainability in fisheries management.Rate this question:

Farming can be more sustainable if soil conditions are improved. Improving soil conditions means improving the structure and balance of the soil.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Improving soil conditions is crucial for making farming more sustainable because it helps enhance the structure and balance of the soil. When soil conditions are improved, it can lead to increased nutrient availability, better water retention, and improved root development, all of which contribute to healthier plants and higher agricultural productivity. Additionally, healthy soil can reduce the need for synthetic fertilizers and pesticides, minimize erosion, and support biodiversity. Therefore, by focusing on improving soil conditions, farmers can adopt more sustainable practices and ensure long-term productivity while minimizing environmental impacts.Rate this question:

The amount of litter on the river bank and how this affects wildlife.
Correct Answer(s)
A. Type of macroinvertebrates present.
B. Physical factors like turbidity, pH and amount of dissolved oxygen in the water.
D. The amount of litter on the river bank and how this affects wildlife.Explanation
The type of macroinvertebrates present and physical factors like turbidity, pH, and amount of dissolved oxygen in the water are direct measurements of the health of the river. Macroinvertebrates are sensitive to changes in water quality, so their presence or absence can indicate the overall health of the ecosystem. Physical factors like turbidity, pH, and dissolved oxygen levels directly affect the water quality and can indicate if the river is polluted or if there are any imbalances in the ecosystem. The amount of litter on the river bank and its impact on wildlife, while important, is not a direct measurement of the health of the river.Rate this question:
