Ecosystem Management Specialist Exam

Which of the following best describes the concept of "ecosystem services"?

• The human efforts to restore ecosystems

• The natural processes that maintain biodiversity

• The benefits humans derive from healthy ecosystems

• The physical infrastructure used to manage ecosystems

What is the primary goal of adaptive management in ecosystem management?

• To maintain the current state of ecosystems

• To increase human interference in natural systems

• To manage ecosystems using a trial-and-error approach while learning from outcomes

• To minimize human involvement in ecological processes

Which of the following is a key characteristic of an invasive species?

• They are native to the ecosystem

• They disrupt ecological balance and biodiversity

• They promote sustainable ecosystem services

• They typically enhance ecosystem productivity

The term "biodiversity" refers to:

• The variety of land uses within an ecosystem

• The diversity of species, genetic diversity, and ecosystem variety

• The genetic variability within a single species

• The specific functional roles of species in an ecosystem

The "precautionary principle" in ecosystem management emphasizes:

• Acting on the assumption that ecosystems are always predictable

• Taking preventive measures when there is uncertainty or potential risk

• Maximizing resource extraction to ensure long-term benefits

• Reducing environmental regulations for economic growth

What is the main function of a "keystone species" in an ecosystem?

• To increase the food supply for all other species

• To help maintain the structure and function of the ecosystem

• To be the dominant predator in the ecosystem

• To support all plant life through pollination

Which of the following is an example of a non-renewable resource?

• Timber

• Freshwater

• Fossil fuels

• Soil

The term "carbon sequestration" refers to:

• The release of carbon dioxide into the atmosphere by plants

• The process by which carbon is stored in forests, oceans, and soil

• The reduction of carbon emissions from vehicles and industries

• The regulation of carbon levels through international treaties

What is the main goal of ecosystem restoration?

• To recreate the exact conditions of a historical ecosystem

• To enhance biodiversity through human intervention

• To recover ecological functions and processes that have been degraded

• To make the ecosystem more resistant to climate change

Which of the following is an example of a "threatened" species?

• A species that has recently gone extinct

• A species at risk of extinction in the near future

• A species that is abundant and widespread

• A species with stable population levels
