Class 8 Practice – Level 3 – Set 1 – Conservation of Plants and Animals

Total questions: 15

What are biodiversity hotspots, and why are they critical for conservation?

Areas with high human population and low species variety

Regions with low biodiversity and industrial growth

Areas with exceptionally high biodiversity that are under threat

Regions rich in minerals and biodiversity

None

How does habitat fragmentation specifically impact wildlife populations?

By creating new ecosystems for animals

By improving migration patterns

By increasing food availability for all species

By isolating populations and reducing genetic diversity

None

Why are invasive species considered a major threat to native biodiversity?

Invasive species only affect plant life.

Invasive species improve the genetic diversity of an ecosystem.

Invasive species are easily eradicated and cause minimal damage.

Invasive species outcompete native species for resources, leading to their decline or extinction.

None

What is the Anthropocene extinction, and why is it a concern for conservation?

A period marked by the extinction of dinosaurs

A natural event caused by volcanic eruptions

A mass extinction event caused primarily by human activities

A future event predicted by climate scientists

None

How does reforestation differ from afforestation, and what is its importance in conservation efforts?

Reforestation involves planting trees in deforested areas, while afforestation involves planting trees in areas that were not previously forests.

Reforestation involves planting trees in a desert, while afforestation involves planting trees in wetlands.

Reforestation and afforestation are identical in terms of process and purpose.

Reforestation only focuses on urban areas, while afforestation focuses on rural areas.

None

Why is the concept of sustainable development important for conserving plants and animals?

It promotes rapid industrialization in biodiversity hotspots.

It encourages unlimited use of natural resources to meet human needs.

It emphasizes the balance between resource consumption and conservation to ensure future generations have access to those resources.

It allows the immediate exploitation of forests and wildlife without restrictions.

None

How does habitat loss contribute to the endangerment of species?

By providing more land for human settlement

By increasing the birth rate of endangered species

By creating new habitats for species to thrive

By limiting the space, food, and shelter available for wildlife, forcing species into smaller, less suitable areas

None

What is the role of the core zone within a biosphere reserve?

It is reserved for industrial development.

It is a tourist area with limited conservation focus.

It is used for farming and agriculture.

It is an area where human activity is strictly prohibited to protect the biodiversity and ecosystems.

None

Why is genetic diversity important for the survival of species?

It increases the population size of species.

It allows species to adapt to changing environmental conditions and resist diseases.

It guarantees that species will never go extinct.

It limits the number of new species in an ecosystem.

None

10.

What makes endemic species particularly vulnerable to extinction?

They are highly adaptable to multiple environments.

They have large population sizes spread across continents.

They are only found in a specific geographic area and depend on that habitat for survival.

They migrate regularly and can survive in different climates.

None

11.

How does climate change pose a threat to global biodiversity?

It decreases the migration patterns of birds.

It causes minor changes in ecosystems without long-term effects.

It alters habitats, disrupts food chains, and increases the frequency of extreme weather events, making survival difficult for many species

It improves biodiversity by creating new ecosystems.

None

12.

How do seed banks contribute to biodiversity conservation?

By providing seeds for commercial agriculture

By storing genetic material of plants to ensure that species can be restored if they become extinct in the wild

By encouraging the commercial trade of rare seeds

By promoting deforestation for seed collection

None

13.

How do biosphere reserves help in both conservation and sustainable development?

By restricting all human activities to protect biodiversity

By allowing tourism and recreational activities without any focus on conservation

By promoting conservation of ecosystems while also allowing local communities to use natural resources sustainably

By focusing only on wildlife conservation with no human involvement

None

14.

Which of the following criteria is used to categorize a species as critically endangered?

The species is found in multiple habitats globally.

The species faces an extremely high risk of extinction in the wild in the immediate future.

The species has no threats and a stable population.

The species is easily adaptable to urban environments.

None

15.

How does the Wildlife Protection Act (1972) of India contribute to conservation?

By allowing commercial use of wildlife resources

By promoting wildlife trade for economic growth

By encouraging the destruction of forests for development

By prohibiting hunting, poaching, and trade of endangered species and protecting their habitats

None
