Which component of an ecosystem captures energy from the sun?
Abiotic factors
Primary producers
Consumers
Decomposers
Primary producers, such as plants and algae, use photosynthesis to convert solar energy into chemical energy. They form the base of food webs and support other trophic levels.
What term describes organisms that break down dead material and recycle nutrients?
Consumers
Decomposers
Scavengers
Producers
Decomposers, such as bacteria and fungi, break down organic matter from dead organisms. This process releases nutrients back into the soil or water, making them available for producers.
Which of the following is an abiotic component of an ecosystem?
Plants
Temperature
Animals
Fungi
Abiotic components are non-living factors in an environment. Temperature, along with light and water, influences the living organisms in an ecosystem.
What is the main human activity leading to deforestation?
Logging for timber
Natural wildfires
Plate tectonics
Soil erosion
Logging for timber removes trees directly for wood products, leading to large-scale deforestation. Natural wildfires and soil erosion also affect forests but are not primarily human-driven on a global scale.
Which practice reduces waste by using items repeatedly instead of discarding them?
Composting
Recycle
Reduction
Reuse
Reuse involves using products or components multiple times in their original form. This practice extends the life of items and reduces waste generation.
Which process best describes eutrophication in aquatic systems?
Excessive nutrient enrichment causing algal blooms
Nutrient depletion preventing plant growth
Increased water turbidity due to sediment
Artificial oxygenation of waterways
Eutrophication occurs when water bodies receive excess nutrients, often nitrogen and phosphorus, leading to algal blooms. The decomposition of these algae depletes oxygen, harming aquatic life.
What is the primary greenhouse gas emitted from burning fossil fuels?
Carbon dioxide (CO2)
Oxygen (O2)
Nitrous oxide (N2O)
Methane (CH4)
Burning fossil fuels such as coal and oil releases large quantities of carbon dioxide into the atmosphere. CO2 is the most significant greenhouse gas driving climate change by trapping heat.
Which policy sets limits on total emissions and allows trading of emission permits?
Cap-and-trade
Carbon tax
Direct regulation of technology
Subsidy for renewables
Cap-and-trade establishes a maximum emissions level and distributes permits that can be traded among emitters. This market-based approach encourages cost-effective reductions.
In the nitrogen cycle, which process converts nitrate to nitrogen gas?
Denitrification
Nitrification
Ammonification
Nitrogen fixation
Denitrification is the microbial process that reduces nitrate to nitrogen gas, completing the nitrogen cycle. This process occurs under anaerobic conditions in soils and sediments.
Which irrigation method is most efficient in reducing water loss?
Sprinkler irrigation
Flood irrigation
Drip irrigation
Furrow irrigation
Drip irrigation delivers water directly to plant roots through a network of tubes, minimizing evaporation and runoff. It is more water-efficient compared to traditional methods.
Which strategy aims to balance resource use without depleting it for future generations?
Conservation
Extraction
Externalization
Exploitation
Conservation involves managing resources sustainably to maintain ecosystem services over the long term. This approach ensures resources remain available for future use.
How do wetlands contribute to nutrient cycling?
They increase salinity in freshwater systems
They primarily generate industrial pollutants
They act as sinks that filter and store nutrients
They decrease biodiversity by trapping nutrients
Wetlands slow water flow, allowing sediments and nutrients to settle and be taken up by plants. This filtering function helps maintain water quality and supports nutrient cycling.
What term describes a species introduced to a new environment causing harm?
Indicator species
Endemic species
Keystone species
Invasive species
Invasive species establish, spread, and cause ecological or economic harm in non-native habitats. Keystone species have disproportionate ecosystem roles but are native.
Which global agreement aims to limit global warming to well below 2°C?
Kyoto Protocol
Paris Agreement
Montreal Protocol
Basel Convention
The Paris Agreement sets targets to limit temperature rise to well below 2°C above pre-industrial levels. It involves nationally determined contributions to reduce greenhouse gas emissions.
Which process describes water moving from plants to the atmosphere?
Condensation
Transpiration
Evaporation
Infiltration
Transpiration is the release of water vapor from plant leaves into the atmosphere. It plays a key role in the water cycle and plant nutrient uptake.
Which indicator is most appropriate for assessing long-term carbon sequestration in forest management?
Biomass carbon stock
Leaf area index
Respiration rate
Net primary productivity
Biomass carbon stock measures the total carbon stored in tree biomass over time. It directly reflects how much carbon forests sequester and retain long-term.
In life cycle assessment, what stage includes raw material extraction to manufacturing?
Gate-to-gate
Cradle-to-gate
Gate-to-grave
Cradle-to-grave
Cradle-to-gate covers stages from resource extraction ('cradle') up to the factory gate before the product is transported. It allows evaluation of upstream environmental impacts.
Which mechanism encourages sustainable agriculture by setting product standards?
Carbon tax
Cap-and-trade
Emission trading
Ecolabeling
Ecolabeling certifies products that meet environmental performance criteria, informing consumers and encouraging sustainable practices. It drives market demand for greener agriculture.
Which process in the phosphorus cycle is primarily mediated by human activity?
Fertilizer runoff
Soil weathering
Organic excretion
Mineral sedimentation
Agricultural fertilizer use increases phosphorus runoff into waterways, accelerating eutrophication. Natural processes like weathering release phosphorus much more slowly.
Which advantage does a carbon tax have over a cap-and-trade system?
Emissions certainty
Price certainty
Market volatility
Permit trading flexibility
A carbon tax sets a predictable price per ton of CO2, giving businesses certainty over costs. Cap-and-trade ensures emission quantities but allows price fluctuations.
