This is the fishing practice done using vessels without or with engines of les than 3 gross tons.
a) Commercial fishing
b) Industrial fishing
c) Artisanal fishing
d) Deep-sea fishing
c) Artisanal fishing
This is the decline in the quality of a habitat, making it less suitable for the species that depend on it.
a) Habitat fragmentation
b) Habitat isolation
c) Habitat degradation
d) Habitat reduction
c) Habitat degradation
This is the introduction of species that can lead to disruptions, migrations, and dispersal degradation.
a) Non-native species
b) Native species
c) Endemic species
d) Indigenous species
a) Non-native species
How does the global economy typically influence local ecosystems?
a) By promoting sustainable resource management.
b) By increasing demand for resources, leading to exploitation.
c) By enhancing local ecosystem resilience.
d) By reducing the scale of human enterprise.
b) By increasing demand for resources, leading to exploitation
Scale of Human Enterprise” is identified as a factor. What does this concept primarily encompass?
a) The size of individual businesses.
b) The impact of human population size and economic activities.
c) The efficiency of resource extraction technologies.
d) The effectiveness of environmental regulations.
b) The impact of human population size and economic activities.
Landscape fragmentation is linked to “highest loss of tree cover.” What is a major implication of this loss for biodiversity?
a) Increased habitat availability for specialist species.
b) Reduced habitat for amphibians, reptiles, and birds.
c) Enhanced ecosystem connectivity.
d) Improved climate regulation.
b) Reduced habitat for amphibians, reptiles, and birds.
The “Spanish regime” is mentioned in the context of “trees were cut and used in the construction of ships.” What does this historical example illustrate?
a) The sustainable use of forest resources.
b) The long-term impact of colonial activities on natural resources.
c) The economic benefits of shipbuilding.
d) The importance of traditional ecological knowledge.
b) The long-term impact of colonial activities on natural resources
This is the phenomenon where the loss of one species triggers the loss of other species within a food web or ecosystem.
a) Species introduction
b) Species migration
c) Extinction cascade
d) Species adaptation
c) Extinction cascade
What is the implication of the “evil quartet” in the biodiversity loss in the Philippines context?
a) It highlights the positive impact of introduced species on native ecosystems.
b) It emphasizes the role of natural disasters as the primary cause of species extinction.
c) It underscores the combined impact of habitat loss, fragmentation, introduced species, and extinction cascades on Philippine biodiversity.
d) It suggests that direct exploitation is the sole driver of biodiversity decline in the region.
c) It underscores the combined impact of habitat loss, fragmentation, introduced species, and extinction cascades on Philippine biodiversity.
How does the consumption of bushmeat potentially impact biodiversity and human health in the Philippines?
a) It promotes the sustainable use of wildlife resources.
b) It serves as a primary source of protein for rural communities without negative consequences.
c) It increases the risk of disease transmission from animals to humans.
d) It enhances the genetic diversity of hunted species.
c) It increases the risk of disease transmission from animals to humans.
What role does fuel wood consumption play in biodiversity loss in the Philippines?
a) It supports the growth of secondary forests and enhances habitat diversity.
b) It reduces the demand for fossil fuels and mitigates climate change impacts.
c) It contributes to deforestation and habitat degradation as a dominant form of biomass energy.
d) It promotes the use of sustainable agroforestry practices.
c) It contributes to deforestation and habitat degradation as a dominant form of biomass energy.
How does the unsustainable use of natural resources impact future generations?
a) It causes minor inconveniences for future resource availability.
b) It leads to potential economic benefits for future societies through resource exploitation.
c) It results in resource depletion, ecosystem degradation, and reduced availability of essential resources for future societies.
d) It generalizes that technological advancements will fully compensate for resource loss.
c) It results in resource depletion, ecosystem degradation, and reduced availability of essential resources for future societies.
Why is the “evil quartet” known as the four principal causes of biodiversity loss?
a) It suggests that habitat changes are part of natural ecological succession.
b) It implies that species introductions are beneficial for ecosystem diversity.
c) It encompasses the combined detrimental effects of habitat loss, fragmentation, introduced species, and extinction cascades.
d) It generalizes that only abiotic factors contribute to biodiversity loss.
c.) It encompasses the combined detrimental effects of habitat loss, fragmentation, introduced species, and extinction cascades.
