Sustainability & Footprints
What does the principle of sustainability aim to do?
Conserve resources and maintain ecosystems for future generations
Variety of life across all levels of organization, from genes to ecosystems.
Biodiveristy
Name one ecosystem service.
Pollination, air/water purification, nutrient cycling, etc.
Which HIPPCO factor involves species introduced to new areas where they outcompete natives?
Invasive species
Science is a systematic process for doing what?
Learning about the world and testing understanding
What does Earth Overshoot Day represent?
The date when human demand exceeds Earth’s capacity to regenerate in a year.
The number of species in an area is called _______
Species richness
Which ecosystem service do decomposers provide?
Nutrient cycling & decomposition
Plastic in oceans choking marine animals is an example of which HIPPCO threat?
Pollution
Which type of science gathers basic info: descriptive or hypothesis-driven?
Descriptive science
List two lifestyle categories that contribute to your ecological footprint.
Carbon, Food, Housing, Goods/Services
What is the species richness?
Bison: 5
Deer: 3
Crane: 23
Rattle Snake: 2
4
Which service prevents erosion and flooding by holding soil in place?
Water filtration & flood control
What does HIPPCO stand for?
Habitat destruction, Invasive species, Pollution, Population growth, Climate change, Overexploitation
Give one example of continuous data.
Any numerical measurement, e.g., temperature, number of species
Why do ecosystems need both abiotic and biotic factors?
They interact to create a balanced ecosystem; biotic organisms rely on abiotic resources for survival, and abiotic conditions are influenced by living things
Give three benefits of biodiversity to humans.
Food, medicine, resilience, tourism, cultural/aesthetic value
How do ecosystems help regulate climate?
Carbon sequestration & stabilization of weather patterns
Which HIPPCO factor is driving sea level rise and coral bleaching?
Climate change
In an experiment, the variable that is manipulated is called the _______.
Independent variable
What is the term used for: the impact of a person or community on the environment, expressed as the amount of land required to sustain their use of natural resources.
Ecological footprint
What does the Shannon-Wiener Diversity Index measure?
Both richness and evenness of species.
The term for: Human demand exceeds Earth’s capacity to regenerate
Earth's Overshoot Day
Explain how overexploitation threatens biodiversity.
Excessive hunting, fishing, or harvesting reduces populations below sustainable levels
In the biodiversity lab, what was the independent variable and dependent variable?
Independent = location, Dependent = biodiversity
