Populations
Which population growth model is described by a line at the top of the graph indicating the population's carrying capacity?
Carrying capacity growth
Logistic growth
Exponential growth rate
Overshoot growth
Which growth model is characterized by a rapid acceleration in population size due to unlimited resources?
Logistic growth
Overshoot growth
Carrying capacity growth
Exponential growth
How do agricultural practices such as monoculture cropping most likely impact soil quality over time?
They increase genetic diversity in crops.
They decrease soil nutrient diversity.
They lead to an increase in topsoil depth due to reduced erosion.
They promote natural pest resistance in plants without human intervention.
Which energy source is typically considered the most sustainable due to its low greenhouse gas emissions and renewable nature?
Nuclear power
Natural gas
Solar power
Coal
What effect does the introduction of an invasive species typically have on native species in an area suffering from habitat loss?
It further threatens native species by competing for limited resources.
It promotes recovery by creating more food sources.
It increases genetic diversity, aiding in survival.
It stabilizes populations through new predator-prey relationships.
How can promoting genetic diversity within managed forests conflict with maximizing short-term economic gains from timber sales?
Genetic diversity decreases susceptibility to pests, ensuring consistent timber yields every year with no drawbacks.
Monoculture forests command higher market prices due to uniform wood quality making them more economically viable than diverse forests.
Increased genetic diversity has no effect since all trees produce similar amounts of marketable wood regardless of species variation.
Planting diverse tree species may reduce harvest efficiency compared to monocultures optimized for quick growth and harvesting.
Which term describes the maximum population size that an environment can sustain indefinitely?
Survivorship curve
Carrying capacity
Biotic potential
Exponential growth

What effect would you expect if there was a significant decrease in primary producers due to disease?
Decreased availability of food for herbivores which could lead to reduced herbivore populations.
Increased plant growth due to decreased competition for sunlight among surviving producers.
A boom in primary producer populations because diseases tend only impact consumers.
Herbivores might switch entirely from plant-based diets towards carnivorous diets.
Balanced ecosystems because secondary consumers would control herbivore populations effectively.
In developing nations where reliance on biomass for fuel contributes significantly to deforestation rates, what measure would best help maintain forest ecosystems while also meeting people's needs fairly?
Providing unlimited subsidies for fossil fuel-based cooking appliances, ignoring accessibility and climate change implications.
Banning all use of biomass as fuel immediately without providing affordable alternatives.
Introducing efficient cookstoves that use less biomass alongside reforestation initiatives involving local communities.
Massive planting of fast-growing non-native tree species for biomass production regardless of potential invasive characteristics.
What happens to the environmental carrying capacity of a region when it implements strict urban sprawl controls and smart growth initiatives?
It promotes rapid industrial development in suburban zones, potentially increasing local pollution levels and undermining gains in environmental quality.
It decreases agricultural production in the outskirts of cities, further straining food supply chains and causing relocation of farmers.
There is a likelihood of witnessing significant population declines in metropolitan areas as people migrate towards rural regions in search of housing.
It tends to increase ecosystem stability, enhance biodiversity, support sustainable management of natural resources, and avoid overextending infrastructure.
