A) Resilience
B) Adaptation
C) Succession
D) Restoration
Correct Answer: A) Resilience
Explanation: Ecosystem resilience is the capacity of an ecosystem to recover from disturbances and maintain its essential functions and processes.
A) Vegetation cover
B) Soil fertility
C) Water runoff
D) Organic matter content
Correct Answer: C) Water runoff
Explanation: Water runoff is a major factor in soil erosion, as it can wash away topsoil and lead to land degradation.
A) Overfishing
B) Ocean acidification
C) Coastal development
D) All of the above
Correct Answer: D) All of the above
Explanation: Coral reefs face multiple threats, including overfishing, ocean acidification, and coastal development, all of which can harm their health and biodiversity.
A) Urbanization
B) Reforestation
C) Afforestation
D) Ecosystem restoration
Correct Answer: A) Urbanization
Explanation: Urbanization involves converting natural land into urban or industrial areas, which can lead to habitat loss and environmental changes.
A) Adaptation
B) Migration
C) Succession
D) Evolution
Correct Answer: C) Succession
Explanation: Succession is the process by which ecological communities gradually change and develop over time, often following disturbances.
A) Monoculture
B) Agroecology
C) Pesticide use
D) Overgrazing
Correct Answer: B) Agroecology
Explanation: Agroecology promotes biodiversity by integrating ecological principles into agricultural practices, enhancing soil health and ecosystem resilience.
A) Global warming
B) Ozone layer depletion
C) Water scarcity
D) Soil erosion
Correct Answer: B) Ozone layer depletion
Explanation: CFCs contribute to the depletion of the ozone layer, which protects the Earth from harmful UV radiation.
A) Photosynthesis
B) Bioremediation
C) Soil erosion
D) Thermal treatment
Correct Answer: B) Bioremediation
Explanation: Bioremediation uses microorganisms to break down pollutants in wastewater, effectively removing contaminants before discharge.
A) Rewilding
B) Afforestation
C) Desertification
D) Urban sprawl
Correct Answer: A) Rewilding
Explanation: Rewilding involves restoring ecosystems by removing invasive species and reintroducing native species to enhance ecological balance and resilience.
A) Bioremediation
B) Phytoremediation
C) Composting
D) Chemical Treatment
Correct Answer: B) Phytoremediation
Explanation: Phytoremediation uses plants to absorb and remove pollutants from contaminated soil or water, helping to clean up environmental contaminants.
A) Strip Cropping
B) Tilling
C) Monoculture
D) Overgrazing
Correct Answer: A) Strip Cropping
Explanation: Strip cropping involves planting crops in alternating strips to reduce soil erosion by slowing water runoff and protecting the soil.
A) Carbon Sequestration
B) Carbon Footprint
C) Carbon Trading
D) Carbon Offset
Correct Answer: A) Carbon Sequestration
Explanation: Carbon sequestration involves capturing carbon dioxide from the atmosphere and storing it underground to reduce greenhouse gas concentrations and mitigate climate change.
A) Flood Irrigation
B) Surface Water Diversion
C) Drip Irrigation
D) Overhead Sprinkling
Correct Answer: C) Drip Irrigation
Explanation: Drip irrigation delivers water directly to plant roots through a network of tubes, reducing water waste and improving efficiency compared to traditional irrigation methods.
A) Hydropower
B) Wind Energy
C) Solar Energy
D) Geothermal Energy
Correct Answer: A) Hydropower
Explanation: Hydropower generates energy by capturing the kinetic energy of flowing or falling water, which is converted into electricity using turbines.
A) Monoculture
B) Agroforestry
C) Clear-Cutting
D) Overuse of Pesticides
Correct Answer: B) Agroforestry
Explanation: Agroforestry integrates trees and shrubs into agricultural systems, which enhances biodiversity, improves soil health, and provides habitat for various species.
A) Mutualism
B) Commensalism
C) Parasitism
D) Competition
Correct Answer: B) Commensalism
Explanation: Commensalism is a type of symbiosis where one species benefits from the relationship, while the other is neither helped nor harmed.
A) Mutualism
B) Commensalism
C) Parasitism
D) Neutralism
Correct Answer: C) Parasitism
Explanation: Parasitism is a relationship where one organism (the parasite) benefits while the other (the host) is harmed.
A) Polyculture
B) Monoculture
C) Succession
D) Niche Partitioning
Correct Answer: A) Polyculture
Explanation: Polyculture involves growing multiple species together, which can enhance ecosystem resilience, reduce pest outbreaks, and improve overall sustainability.
A) Keystone Species
B) Endemic Species
C) Invasive Species
D) Pioneer Species
Correct Answer: C) Invasive Species
Explanation: Invasive species are non-native organisms that spread rapidly in new environments and can disrupt local ecosystems, outcompete native species, and cause ecological damage.
A) Species Crisis
B) Extinction Vortex
C) Biodiversity Decline
D) Ecosystem Collapse
Correct Answer: B) Extinction Vortex
Explanation: An extinction vortex occurs when habitat loss and fragmentation lead to reduced species populations and genetic diversity, increasing the risk of extinction and further ecosystem degradation.
