Biodiversity and Conservation Questions
What is the main threat to biodiversity in the Eastern Himalayas?
-
Habitat loss
-
Climate change
-
Pollution
-
Invasive species
A
Correct answer
Explanation
Habitat loss is the main threat to biodiversity in the Eastern Himalayas. The region has experienced extensive deforestation for agriculture, logging, and mining.
What is the primary cause of habitat loss?
-
Natural disasters
-
Climate change
-
Human activities
-
Pollution
C
Correct answer
Explanation
Human activities such as deforestation, urbanization, and agriculture are the leading causes of habitat loss.
Which of the following is NOT a consequence of habitat loss?
-
Loss of biodiversity
-
Increased soil erosion
-
Improved air quality
-
Disruption of water cycles
C
Correct answer
Explanation
Habitat loss can lead to a loss of biodiversity, increased soil erosion, and disruption of water cycles, but it does not improve air quality.
Which type of habitat is most vulnerable to loss and fragmentation?
-
Forests
-
Grasslands
-
Wetlands
-
Deserts
C
Correct answer
Explanation
Wetlands are among the most vulnerable habitats to loss and fragmentation due to their unique ecological characteristics and the high demand for land for development.
Which of the following is NOT a potential impact of habitat fragmentation on species?
-
Reduced genetic diversity
-
Increased risk of inbreeding
-
Improved dispersal and colonization abilities
-
Increased vulnerability to predators
C
Correct answer
Explanation
Habitat fragmentation can lead to reduced genetic diversity, increased risk of inbreeding, and increased vulnerability to predators, but it does not improve dispersal and colonization abilities.
Which of the following is NOT a potential impact of habitat degradation on species?
-
Reduced reproductive success
-
Increased susceptibility to disease
-
Improved foraging efficiency
-
Reduced carrying capacity
C
Correct answer
Explanation
Habitat degradation can lead to reduced reproductive success, increased susceptibility to disease, and reduced carrying capacity, but it does not improve foraging efficiency.
Which of the following is NOT a potential impact of habitat conversion on species?
-
Loss of specialized adaptations
-
Increased competition for resources
-
Improved access to food and shelter
-
Reduced genetic diversity
C
Correct answer
Explanation
Habitat conversion can lead to loss of specialized adaptations, increased competition for resources, and reduced genetic diversity, but it does not improve access to food and shelter.
Which of the following is NOT a potential benefit of habitat creation?
-
Increased biodiversity
-
Improved connectivity between habitats
-
Reduced human-wildlife conflict
-
Increased competition for resources
D
Correct answer
Explanation
Habitat creation can lead to increased biodiversity, improved connectivity between habitats, and reduced human-wildlife conflict, but it may also lead to increased competition for resources among species.
Which of the following is NOT a potential benefit of habitat enhancement?
-
Increased carrying capacity
-
Improved reproductive success
-
Reduced susceptibility to disease
-
Increased genetic diversity
D
Correct answer
Explanation
Habitat enhancement can lead to increased carrying capacity, improved reproductive success, and reduced susceptibility to disease, but it does not typically lead to increased genetic diversity.
What is the primary cause of habitat loss?
-
Climate change
-
Pollution
-
Human activities
-
Natural disasters
C
Correct answer
Explanation
Human activities such as deforestation, urbanization, and agriculture are the primary causes of habitat loss.
Which of the following is NOT a consequence of habitat loss?
-
Loss of biodiversity
-
Increased pollution
-
Climate change
-
Spread of invasive species
C
Correct answer
Explanation
Climate change is not a direct consequence of habitat loss, although it can be a contributing factor.
How does habitat loss affect the survival of species?
-
Reduces food availability
-
Increases competition for resources
-
Makes them more susceptible to disease
-
All of the above
D
Correct answer
Explanation
Habitat loss can have multiple negative effects on species survival, including reducing food availability, increasing competition for resources, and making them more susceptible to disease.
Which type of habitat is most vulnerable to loss?
-
Forests
-
Grasslands
-
Wetlands
-
Deserts
C
Correct answer
Explanation
Wetlands are among the most vulnerable habitats to loss due to their unique ecological characteristics and the high demand for land for development.
What is the term used to describe the process of species becoming extinct due to habitat loss?
-
Endangered species
-
Habitat fragmentation
-
Extinction vortex
-
Habitat destruction
C
Correct answer
Explanation
Extinction vortex refers to the process where habitat loss leads to a decline in population size, which in turn increases the risk of extinction.
How does habitat loss impact ecosystem services?
-
Decreased water purification
-
Reduced carbon sequestration
-
Loss of pollination services
-
All of the above
D
Correct answer
Explanation
Habitat loss can lead to decreased water purification, reduced carbon sequestration, loss of pollination services, and other disruptions to ecosystem services.
