Sample cards from this deck

Definition
Ecosystems and Biodiversity - TCE Environmental Science (Tasmania)
Define Keystone species
A keystone species has a disproportionately large effect on its ecosystem relative to its abundance, so its removal causes major change. The sea otter is a classic global example; in Tasmanian giant kelp forests, sea urchin grazing pressure illustrates how losing predators reshapes an ecosystem.
Definition
Agriculture, Food Production and Land Use - TCE Environmental Science (Tasmania)
Define Eutrophication
Eutrophication is the over-enrichment of water with nutrients, especially nitrogen and phosphorus from fertiliser or waste, which triggers excessive algal growth. When the algae die and decompose, oxygen is stripped from the water, killing fish and other aquatic life.
Definition
Biodiversity Loss and Introduced Species - TCE Environmental Science (Tasmania)
Define Invasive species
An invasive species is a non-native organism that establishes and spreads in a new environment, causing harm to native species, ecosystems or human interests because local species lack defences against it.
Definition
Environmental Law, Policy and Stakeholders - TCE Environmental Science (Tasmania)
Define Stakeholder
A stakeholder is any individual or group with an interest in, or who is affected by, an environmental issue or decision, such as governments, industries, local communities, Aboriginal people, scientists and conservation organisations.
Definition
Population and Community Dynamics - TCE Environmental Science (Tasmania)
Define Carrying capacity
Carrying capacity is the largest population of a species that an environment can support indefinitely without its resources being permanently degraded.
Definition
Ecosystem Services and Resource Use - TCE Environmental Science (Tasmania)
Define Ecosystem services
Ecosystem services are the direct and indirect benefits that humans obtain from functioning ecosystems, including the provision of resources, the regulation of natural processes, and cultural and supporting roles.
Definition
Climate Change and the Enhanced Greenhouse Effect - TCE Environmental Science (Tasmania)
Define Enhanced greenhouse effect
The enhanced greenhouse effect is the additional warming caused when human activities increase the concentration of greenhouse gases, trapping more heat than the natural greenhouse effect alone.
Definition
Environmental Monitoring and Fieldwork - TCE Environmental Science (Tasmania)
Define Reliability and validity
Reliability is the consistency of results when a measurement is repeated under the same conditions. Validity is whether the method actually measures what it is intended to measure.
Key fact
Energy Flow and Nutrient Cycling - TCE Environmental Science (Tasmania)
Tell me about Energy flow and trophic levels
Almost all ecosystems run on energy from the Sun. Producers (autotrophs) such as plants, algae and phytoplankton use photosynthesis to convert light energy into chemical energy stored in organic molecules.
Definition
Human Population Growth and Ecological Footprint - TCE Environmental Science (Tasmania)
Define Demographic transition
The demographic transition is the shift a population undergoes as a country develops, moving from high birth and death rates, through a phase of rapid growth where deaths fall before births, to low birth and death rates and a stable or shrinking population.
