Q1
Easy
What is the highest level of biodiversity?
A. Genetic diversity
B. Species diversity
C. Ecosystem diversity
D. Habitat diversity
Show Answer & Explanation
Correct Answer: C
Ecosystem diversity encompasses the variety of ecosystems within a region. It represents the highest level of biodiversity because it includes variations in habitats, communities, and ecological processes.
Q2
Easy
Which term describes the variety of species within a specific habitat?
A. Genetic diversity
B. Species diversity
C. Ecosystem diversity
D. Population diversity
Show Answer & Explanation
Correct Answer: B
Species diversity refers to the variety of species present in a specific habitat or ecosystem. It is crucial for maintaining ecosystem stability and resilience.
Q3
Easy
Which of the following is an example of genetic diversity?
A. Different species of birds in a forest
B. Varieties of rice cultivated in a region
C. Types of forests in a country
D. Different ecosystems in a biome
Show Answer & Explanation
Correct Answer: B
Genetic diversity refers to the variation of genes within the same species. Different varieties of rice have genetic variations that allow for adaptability and resilience.
Q4
Medium
Which level of biodiversity is most commonly measured by the variety of species in a given area?
A. Genetic diversity
B. Species diversity
C. Ecosystem diversity
D. Functional diversity
Show Answer & Explanation
Correct Answer: B
Species diversity refers to the variety and abundance of species present in a specific area, making it the most commonly measured level of biodiversity.
Q5
Medium
What is the primary reason for the decline in biodiversity at the ecosystem level?
A. Natural disasters
B. Habitat destruction
C. Climate change
D. Pollution
Show Answer & Explanation
Correct Answer: B
Habitat destruction is the leading cause of biodiversity loss at the ecosystem level, as it directly removes the environments necessary for various species to thrive.
Q6
Medium
Which of the following best describes genetic diversity?
A. Variations in species composition
B. Variety of ecosystems
C. Differences in genetic makeup within a species
D. Diversity of habitats
Show Answer & Explanation
Correct Answer: C
Genetic diversity refers to the differences in genetic makeup among individuals within a species, which is essential for adaptability and survival.
Q7
Medium
Which of the following practices helps in conserving biodiversity at multiple levels?
A. Monoculture farming
B. Creating wildlife corridors
C. Urbanization
D. Deforestation
Show Answer & Explanation
Correct Answer: B
Creating wildlife corridors facilitates the movement of species between habitats, thereby promoting genetic diversity and ecosystem stability, crucial for conservation.
Q8
Hard
Which level of biodiversity is primarily concerned with the variety of species within a specific ecosystem?
A. Genetic diversity
B. Species diversity
C. Ecosystem diversity
D. Functional diversity
Show Answer & Explanation
Correct Answer: B
Species diversity refers to the variety of species in a specific area or ecosystem, which is crucial for understanding the richness and complexity of that ecosystem.
Q9
Hard
In a given habitat, if the Simpson Diversity Index is calculated to be 0.8, what does this suggest about the biodiversity of that habitat?
A. High species richness and evenness
B. Low species richness and evenness
C. High species richness but low evenness
D. Low species richness but high evenness
Show Answer & Explanation
Correct Answer: A
A Simpson Diversity Index close to 1 indicates high biodiversity, meaning both species richness and evenness are high in the habitat.
Q10
Hard
Which of the following levels of biodiversity is most likely to be impacted by habitat destruction?
A. Genetic diversity
B. Species diversity
C. Ecosystem diversity
D. Functional diversity
Show Answer & Explanation
Correct Answer: C
Habitat destruction directly affects ecosystem diversity by altering the physical environment and the interactions among species, leading to loss of habitat and ecosystem functions.
