Populations
How might a population with a pyramid-shaped age structure diagram affect land-use in the future?
Increased demand for housing and urban development due to a growing younger population
Expansion of conservation areas as environmental awareness rises among youth
Decreased agricultural land use owing to advancements in farming technology
Reduction in mining activities due to depletion of natural resources
Which energy source typically emits the least greenhouse gases but has been controversial due to concerns about radioactive waste?
Biomass
Nuclear power
Natural gas
Coal
An age structure diagram with a narrow base and a narrow top suggests a population with:
Low birth rates and high mortality rates
Low birth rates and low mortality rates
High birth rates and low mortality rates
High birth rates and high mortality rates
What impact does high fertility rates evident in an age structure diagram have on local ecosystems?
Lower carbon emissions per capita because of economies of scale in family units
Greater resource extraction leading to habitat destruction due to increased population demands
More efficient land use as communities adapt to higher populations with limited space
Enhanced reforestation efforts as families engage in sustainable agriculture practices
If a country has an age structure diagram with a broad base that quickly narrows, what could be a potential long-term environmental policy focus for this country?
Increasing funding for retirement and pension plans to support economic stability.
Prioritizing urban development to accommodate decreasing population density.
Expanding the health care services for an aging population.
Investing in sustainable educational programs to manage future population growth.
Which renewable energy source can potentially lead to habitat destruction if not properly managed?
Geothermal power
Wind power
Solar power
Hydropower
What method could effectively assess how ocean acidification selectively impacts different life stages within mollusk populations?
Compare fossil records with modern specimens ignoring live population dynamics and acidification trends.
Track adult mollusk mortality rates post-acidification event without consideration for early developmental impacts.
Monitor pH levels alone while disregarding stage-specific vulnerability within mollusk life cycles.
Employ carbonate chemistry profiles correlated with larval settlement rates and shell growth patterns across multiple generations.

An age structure diagram with a narrow base and a wide top is most likely to be observed in a population that:
Has a declining birth rate and a low life expectancy
Has a declining birth rate and a high life expectancy
Has a high birth rate and a high life expectancy
Has a high birth rate and a low life expectancy
How would you describe a country with almost equal proportions across all ages in its age structure diagram?
It has a stable or zero growth rate.
It is experiencing rapid growth.
It has extremely high fertility rates.
Its economy is predominantly agricultural-based.
In nations where there is significant rural-to-urban migration evident by their age structure diagrams, how might this demographic shift affect local attitudes towards forest preservation?
Urban residents form lobbying groups to resist forest conservation, viewing it as an obstacle to development.
Migration leads to higher valuation of forest products, promoting commercial exploitation.
Urbanization trends often diminish direct reliance on forests, thus potentially fostering greater support for preservation initiatives.
Rural depopulation reduces human pressure on forests, making preservation less critical.
