Which of the following scenarios best illustrates the ecological value of biodiversity?
Which of the following scenarios best illustrates the ecological value of biodiversity?
- A community organizes a nature walk to promote the spiritual benefits of connecting with local ecosystems.
- A pharmaceutical company discovers a new compound in a rare plant species that can cure a common disease.
- A diverse forest ecosystem demonstrates resilience to a disease outbreak, preventing widespread tree mortality. (correct)
- A local market sells a variety of fruits and vegetables, contributing to the region's agricultural economy.
How does nutrient loading negatively impact aquatic biodiversity?
How does nutrient loading negatively impact aquatic biodiversity?
- It increases the oxygen levels in the water, benefiting all aquatic life.
- It causes eutrophication, which depletes oxygen and harms aquatic animals. (correct)
- It filters out pollutants, resulting in cleaner water for aquatic organisms.
- It leads to decreased plant growth, creating more open space for aquatic animals.
What is a likely consequence of overexploitation on the genetic diversity of a species?
What is a likely consequence of overexploitation on the genetic diversity of a species?
- Increased gene flow and adaptation to new environments.
- Greater ability to compete with invasive species for resources.
- Enhanced resilience to environmental stressors due to increased population size.
- Reduced genetic variation, making the species more vulnerable to diseases and environmental changes. (correct)
Which of the following scenarios provides the best example of how habitat loss impacts biodiversity?

Study Notes
- Biodiversity is based on the interactions between living organisms and abiotic factors.
- A reduction in biodiversity destabilizes ecosystems, weakens natural cycles, and increases vulnerability to extreme events.
- Biodiversity is valuable because it provides all the necessities of life and forms the basis for the economy.
- Everything bought and sold comes from the natural world.
- Most people connect with nature on a personal or spiritual level.
- Losing biodiversity can disrupt this connection.
Major Threats to Biodiversity
- Pollution/nutrient loading causes bioaccumulation leading to toxicity.
- Nutrient loading results in increased plant growth (eutrophication).
- This deprives other plants and aquatic animals of oxygen.
- Overexploitation from fishing and hunting reduces species to low levels.
- Habitat loss in habitat places reduces organism survivability.
- Invasive species are new organisms in an area that have not adapted, causing increased competition for native organisms.
- Climate change increases air temperature, disrupting a species' natural niche and range of tolerance.

Description
Biodiversity relies on the interactions of living organisms and abiotic factors. When biodiversity is reduced, ecosystems are destabilized which can cause extreme events. Major threats to biodiversity include pollution, overexploitation, habitat loss and invasive species.
