The Living World: Ecosystems
What strategy would be most effective in preventing desertification in semi-arid grassland biomes due to overgrazing?
Construction of windbreaks to control soil erosion caused by livestock
Supplemental feeding programs that reduce reliance on native vegetation
Introduction of hardy plant species intended to outcompete overgrazed native plants
Rotational grazing systems that allow vegetation recovery periods
In which biome would you expect to find wide-ranging herds of grazing animals like zebras and antelopes?
Tropical rainforest
Taiga
Arctic tundra
Savanna
Which policy initiative aims primarily at reducing desertification but also has implications for carbon storage?
Advocating for widespread clear-cutting methods
Promotion of the use of fossil fuels over biofuels
Encouraging sustainable grazing practices
Supporting deep-sea mining operations
Which biome has few green trees or plants and rich soil composition?
Savanna.
Tundra.
Temperate Rainforest.
Tropical Rainforest.
Considering biodiversity conservation when choosing an energy source, which option has potentially significant habitat disruption due to its infrastructure requirements?
Rooftop solar panels
Tidal wave generators
Biofuel crop cultivation
Offshore wind farms
In attempting to mitigate desertification due to overgrazing, what consideration should be taken into account regarding socioeconomic impacts?
Offer financial compensation tied directly loss livestock numbers potentially promoting unsustainable breeding practices.
Develop alternative livelihood programs such as drought-resistant crop farming aid income diversification among herders.
Enforce strict grazing limits universally ignoring variations in herd sizes across different socio-economic groups.
Encourage widespread reforestation initiatives disregarding whether tree planting is culturally relevant or practical locally.
What process would be most directly accelerated following a fire that clears large areas of chaparral biome vegetation?
Carbon sequestration as newly exposed soils rapidly absorb atmospheric CO.
Primary succession initiating soil formation and pioneer species colonization.
Albedo effect reduction causing increased solar heat retention at ground level.
Secondary succession leading to community reestablishment over time.

Which scenario illustrates the complex relationship between invasive species control and maintaining biodiversity in temperate forests?
Increasing tourism funding conservation yet potentially disrupting habitats through infrastructure development.
Introducing predators may control pest populations but can also threaten native species.
Enhanced CO2 absorption methods improving forest growth but reducing underbrush needed by some fauna.
Fire suppression techniques preventing natural clearing but increasing vulnerability to large-scale wildfires.
Which of the following is a primary challenge in managing resources sustainably within a tropical rainforest?
Implementing wide-scale irrigation systems for agricultural expansion.
Predicting annual snowfall patterns to ensure consistent water supply.
Balancing economic gains from logging with biodiversity conservation.
Developing frost-resistant plant varieties for local agriculture.
What trade-off might result from converting a natural wetland into agricultural land?
Greater long-term carbon storage due to crop production
Increase in local biodiversity due to new habitats
Increased water availability for surrounding ecosystems because of irrigation
Loss of natural flood control and filtration services
