Biodiversity and Ecosystem Resilience Quiz

How does high biodiversity contribute to the resilience of an ecosystem?

• It increases the competition for resources

• It helps ecosystems recover more quickly from disturbances

• It reduces the need for species to adapt to environmental changes

Which factor would most likely lead to a population exceeding its carrying capacity?

• A decrease in resource availability

• An increase in biodiversity

• A decrease in population density

Why is population density important in understanding the health of an ecosystem?

• It determines the number of different species present

• It indicates how crowded a population is and potential competition for resources

• It measures the genetic variation within a species

Which of the following is an example of a limiting factor for a population?

• The rate of immigration

• The availability of food, water, and shelter

• The carrying capacity of the species

What is the primary consequence when a population exceeds its environment’s carrying capacity?

• The population thrives and grows indefinitely

• The environment becomes degraded, leading to a population decline

• The ecosystem becomes more stable and balanced

In the context of biodiversity, what does ecosystem stability refer to?

• The ability of an ecosystem to remain unchanged over time

• The ability of an ecosystem to recover from disturbances due to complex species interactions

• The number of species present in an ecosystem

How does deforestation affect biodiversity in the Philippines?

• It increases the number of species by creating new habitats

• It leads to the destruction of habitats, causing species to become endangered

• It improves air quality and promotes species health

What is the relationship between population dynamics and environmental changes?

• A stable population cannot be affected by environmental changes

• Changes in birth rates, death rates, and migration can lead to shifts in population size

• Population dynamics have no significant effect on the environment

How does water pollution contribute to the decline of biodiversity in aquatic ecosystems?

• By providing more nutrients that increase plant growth

• By causing eutrophication, which depletes oxygen levels and harms aquatic life

• By improving the health of aquatic species

What is the most direct impact of air pollution on biodiversity?

• It stabilizes ecosystems by reducing harmful gases

• It contributes to global warming, disrupting ecosystems and leading to species migration or extinction

• It enhances the resilience of ecosystems to changes
