Environmental Science Q&A by dot point
A short Q&A bank for every TAS Environmental Science syllabus dot point. Each question and answer is drawn directly from our worked dot-point page, so you can scan key concepts before opening the long-form answer.
Ecological Processes
Describe the structure of ecosystems and explain why biodiversity at gene, species and ecosystem levels matters for ecological function.
Explain energy flow through trophic levels and the cycling of carbon, nitrogen and water, and interpret food webs and ecological pyramids.
Explain the factors that regulate population size and describe the main interactions between species, including competition, predation, mutualism and succession.
Human Dependence and Impact on Ecosystems
Explain how agriculture, aquaculture and food production depend on ecosystem processes, and describe the environmental impacts of intensive land and water use.
Describe the ecosystem services humans rely on and explain how resource use such as forestry, fishing and agriculture affects Tasmanian ecosystems.
Explain how human population growth and patterns of consumption drive environmental impact, and describe how the ecological footprint measures the demand humans place on the biosphere.
Describe the main types and sources of pollution, explain how pollutants such as nutrients, plastics and toxins affect ecosystems, and evaluate waste management strategies.
Local and Global Changes to Ecosystems
Explain the major causes of biodiversity loss, including habitat change, introduced species and disease, and describe their effects on Tasmanian ecosystems.
Explain the greenhouse effect and the enhanced greenhouse effect, and describe the observed and projected impacts of climate change on Tasmanian and global ecosystems.
Explain the causes and consequences of land clearing, deforestation and habitat fragmentation for biodiversity, carbon and ecosystem function.
Explain the role of the ozone layer, how human-made chemicals cause ozone depletion, and how international action has begun to reverse it.
Principles for Ecologically Sustainable Management
Describe the roles of law, policy and stakeholders in environmental management, and explain how evidence-based decisions about contemporary issues are made.
Describe environmental monitoring methods and fieldwork techniques, and explain how reliable, valid data is collected, analysed and used in environmental decision-making.
Explain the principles of ecologically sustainable development, including the precautionary principle, intergenerational and intragenerational equity, and conservation of biodiversity, and apply them to environmental decisions.
Explain the principles of ecologically sustainable development and evaluate conservation and management strategies used to protect Tasmanian ecosystems.
