9th Zoology-Biodiversity

Why is genetic diversity crucial for the survival and adaptation of species?

• It helps to maintain a healthy and balanced environment
• It allows for greater resilience to environmental changes
• It provides a wider range of traits within a species
• It supports a unique set of species in each ecosystem

Which of the following is NOT a measure of life's variations that contribute to biodiversity?

• Ecosystem diversity
• Population diversity
• Genetic diversity
• Species diversity

What is the main difference between species diversity and genetic diversity?

• Species diversity refers to the number of different species, while genetic diversity refers to the variation in genes within a population
• Species diversity refers to the variety of different ecosystems within a region, while genetic diversity refers to the variety of traits within a species
• Species diversity refers to the variation in genes within a population, while genetic diversity refers to the number of different species
• Species diversity refers to the variety of traits within a species, while genetic diversity refers to the variety of different ecosystems within a region

What is overexploitation?

• The destruction of natural habitats
• The contamination of air, water, and soil
• The depletion of resources
• The altering climate patterns

Why is it important to understand and protect biodiversity for the future of our planet?

• To prevent the negative impacts of human activities
• To maintain a healthy and balanced environment
• To ensure the survival of all species
• All of the above

Which of the following is NOT a negative impact of human activities on biodiversity?

• Pollution
• Habitat loss and fragmentation
• Overexploitation
• Climate change

What does ecosystem diversity refer to?

• The variation in genes within a population
• The number of different species in a given area
• The variety of different ecosystems within a region
• The variety of traits within a species

How does climate change pose a threat to biodiversity?

• It increases the risk of extinction
• It affects species' behavior
• It disrupts habitats
• All of the above

Which of the following is NOT a consequence of biodiversity loss?

• Increase in genetic diversity
• Extinction of species
• Disruption of ecosystems
• Decrease in ecosystem services

What is the main cause of habitat loss and fragmentation?

• Climate change
• Pollution
• Deforestation
• Overexploitation
