Which of the following agricultural practices is a major contributor to habitat fragmentation?

  1. Crop rotation

  2. Sustainable farming

  3. Agroforestry

  4. Clear-cutting


Correct Option: D
Explanation:

Clear-cutting, the practice of removing all trees from a forest, is a major cause of habitat fragmentation as it creates large, contiguous areas of cleared land that disrupt natural ecosystems and isolate wildlife populations.

How does habitat fragmentation impact biodiversity?

  1. It increases genetic diversity.

  2. It reduces the number of species in an ecosystem.

  3. It promotes the spread of invasive species.

  4. It enhances the resilience of ecosystems.


Correct Option: B
Explanation:

Habitat fragmentation reduces biodiversity by isolating populations, limiting their ability to interact and reproduce, and making them more vulnerable to extinction.

Which of the following is a consequence of habitat fragmentation for wildlife populations?

  1. Increased genetic diversity

  2. Reduced dispersal and migration

  3. Enhanced predator-prey interactions

  4. Improved access to food resources


Correct Option: B
Explanation:

Habitat fragmentation reduces the ability of wildlife to disperse and migrate, as they face barriers such as roads, fences, and cleared land, which can lead to population isolation and genetic bottlenecks.

What is the term used to describe the process by which small, isolated patches of habitat are created due to habitat fragmentation?

  1. Habitat connectivity

  2. Habitat restoration

  3. Habitat fragmentation

  4. Habitat isolation


Correct Option: D
Explanation:

Habitat isolation refers to the process where once-connected habitats become separated into smaller, isolated patches due to human activities like agriculture, urbanization, and infrastructure development.

Which agricultural practice can help mitigate the negative impacts of habitat fragmentation?

  1. Monoculture farming

  2. Intensive livestock grazing

  3. Agroforestry

  4. Slash-and-burn agriculture


Correct Option: C
Explanation:

Agroforestry, the integration of trees and crops or livestock on the same land, can help mitigate habitat fragmentation by providing connectivity between fragmented habitats and supporting biodiversity.

How does habitat fragmentation affect ecosystem services provided by natural habitats?

  1. It enhances water purification and filtration.

  2. It increases carbon sequestration and storage.

  3. It promotes soil erosion and nutrient loss.

  4. It improves air quality and climate regulation.


Correct Option: C
Explanation:

Habitat fragmentation can lead to soil erosion and nutrient loss as the removal of vegetation and the creation of fragmented landscapes reduce the ability of ecosystems to retain soil and nutrients.

Which of the following is NOT a potential consequence of habitat fragmentation for human populations?

  1. Increased risk of zoonotic diseases

  2. Reduced access to clean water resources

  3. Enhanced food security and agricultural productivity

  4. Loss of traditional livelihoods and cultural practices


Correct Option: C
Explanation:

Habitat fragmentation can have negative impacts on food security and agricultural productivity as it reduces the availability of natural resources, disrupts ecosystem services, and can lead to conflicts between humans and wildlife.

What is the term used to describe the process of reconnecting fragmented habitats to restore ecological connectivity?

  1. Habitat fragmentation

  2. Habitat isolation

  3. Habitat restoration

  4. Habitat connectivity


Correct Option: D
Explanation:

Habitat connectivity refers to the process of reconnecting fragmented habitats to allow for the movement and dispersal of species, genetic material, and ecological processes across the landscape.

Which agricultural practice involves the conversion of natural habitats, such as forests, into agricultural land?

  1. Agroforestry

  2. Sustainable farming

  3. Conservation agriculture

  4. Land clearing


Correct Option: D
Explanation:

Land clearing, also known as deforestation, is the process of removing natural vegetation, often forests, to make way for agricultural activities or other land uses.

How does habitat fragmentation impact the ability of species to adapt to changing environmental conditions?

  1. It increases their resilience and adaptability.

  2. It reduces their genetic diversity and adaptability.

  3. It enhances their ability to disperse and colonize new areas.

  4. It improves their access to food and water resources.


Correct Option: B
Explanation:

Habitat fragmentation reduces genetic diversity within populations, making them less resilient and adaptable to environmental changes, such as climate change or disease outbreaks.

Which of the following is NOT a potential strategy for mitigating the impacts of habitat fragmentation on biodiversity?

  1. Establishing wildlife corridors and green infrastructure

  2. Promoting sustainable agricultural practices

  3. Reducing the use of pesticides and fertilizers

  4. Increasing the size and number of protected areas


Correct Option: C
Explanation:

While reducing the use of pesticides and fertilizers is important for sustainable agriculture, it is not directly related to mitigating the impacts of habitat fragmentation on biodiversity.

What is the term used to describe the process by which species lose their ability to survive and reproduce in fragmented habitats?

  1. Habitat isolation

  2. Habitat fragmentation

  3. Habitat degradation

  4. Habitat loss


Correct Option: D
Explanation:

Habitat loss refers to the reduction or disappearance of suitable habitats for a species, often due to human activities such as agriculture, urbanization, and deforestation.

How does habitat fragmentation affect the ability of predators to control prey populations?

  1. It increases the efficiency of predators in controlling prey populations.

  2. It reduces the ability of predators to locate and capture prey.

  3. It enhances the ability of prey to escape from predators.

  4. It promotes the coexistence of predators and prey species.


Correct Option: B
Explanation:

Habitat fragmentation can reduce the ability of predators to locate and capture prey as it disrupts their hunting patterns and makes it more difficult for them to navigate through fragmented landscapes.

Which of the following is NOT a potential consequence of habitat fragmentation for ecosystem functioning?

  1. Disruption of nutrient cycling and decomposition processes

  2. Increased resilience and stability of ecosystems

  3. Alteration of water flow and hydrological processes

  4. Changes in species interactions and community structure


Correct Option: B
Explanation:

Habitat fragmentation typically reduces the resilience and stability of ecosystems by disrupting ecological processes and reducing biodiversity.

What is the term used to describe the process by which fragmented habitats are restored and reconnected to create a more continuous landscape?

  1. Habitat fragmentation

  2. Habitat isolation

  3. Habitat restoration

  4. Habitat connectivity


Correct Option: C
Explanation:

Habitat restoration refers to the process of repairing and improving degraded or fragmented habitats to restore their ecological functions and support biodiversity.
