What is the primary cause of biodiversity loss in urban areas?

  1. Habitat destruction

  2. Pollution

  3. Climate change

  4. Overpopulation


Correct Option: A
Explanation:

Habitat destruction is the primary cause of biodiversity loss in urban areas, as it eliminates the natural habitats of various species, leading to their decline and potential extinction.

Which of the following is NOT a consequence of biodiversity loss in urban areas?

  1. Loss of ecosystem services

  2. Increased air pollution

  3. Reduced water quality

  4. Improved human health


Correct Option: D
Explanation:

Biodiversity loss in urban areas can have various negative consequences, including the loss of ecosystem services, increased air pollution, and reduced water quality. However, it does not directly lead to improved human health.

Which of the following is an example of a species that has been negatively impacted by biodiversity loss in urban areas?

  1. House sparrow

  2. Pigeon

  3. Crow

  4. Myna


Correct Option: A
Explanation:

The house sparrow is an example of a species that has been negatively impacted by biodiversity loss in urban areas. It is a common bird found in urban environments, but its populations have declined due to habitat loss, pollution, and competition from other species.

What is the term used to describe the process of introducing non-native species into an ecosystem?

  1. Invasive species introduction

  2. Habitat fragmentation

  3. Pollution

  4. Climate change


Correct Option: A
Explanation:

Invasive species introduction is the term used to describe the process of introducing non-native species into an ecosystem. These species can have negative impacts on native biodiversity by competing for resources, transmitting diseases, or altering the ecosystem's structure and function.

Which of the following is an example of a conservation strategy aimed at preserving biodiversity in urban areas?

  1. Creating green spaces

  2. Reducing pollution

  3. Controlling invasive species

  4. All of the above


Correct Option: D
Explanation:

Creating green spaces, reducing pollution, and controlling invasive species are all examples of conservation strategies aimed at preserving biodiversity in urban areas. These strategies help to protect and restore natural habitats, reduce the impacts of human activities, and promote the coexistence of native species.

What is the term used to describe the loss of genetic diversity within a population?

  1. Genetic erosion

  2. Habitat fragmentation

  3. Invasive species introduction

  4. Pollution


Correct Option: A
Explanation:

Genetic erosion is the term used to describe the loss of genetic diversity within a population. This can occur due to various factors, such as habitat loss, fragmentation, and the introduction of non-native species, and can have negative consequences for the population's resilience and adaptability.

Which of the following is NOT a potential solution to address biodiversity loss in urban areas?

  1. Promoting sustainable urban development

  2. Educating the public about biodiversity conservation

  3. Implementing strict environmental regulations

  4. Encouraging the use of pesticides and herbicides


Correct Option: D
Explanation:

Promoting sustainable urban development, educating the public, and implementing strict environmental regulations are all potential solutions to address biodiversity loss in urban areas. However, encouraging the use of pesticides and herbicides is not a solution, as these chemicals can have negative impacts on biodiversity and the environment.

What is the term used to describe the process of dividing a natural habitat into smaller and isolated fragments?

  1. Habitat fragmentation

  2. Invasive species introduction

  3. Pollution

  4. Climate change


Correct Option: A
Explanation:

Habitat fragmentation is the term used to describe the process of dividing a natural habitat into smaller and isolated fragments. This can occur due to human activities such as urbanization, agriculture, and infrastructure development, and can have negative impacts on biodiversity by reducing the size and connectivity of habitats.

Which of the following is an example of a keystone species in urban ecosystems?

  1. Honeybee

  2. Earthworm

  3. Pigeon

  4. Crow


Correct Option: A
Explanation:

The honeybee is an example of a keystone species in urban ecosystems. As pollinators, honeybees play a crucial role in the reproduction of many plant species, including those that provide food and shelter for other organisms. Their decline can have cascading effects on biodiversity and ecosystem functioning.

What is the term used to describe the process of restoring a degraded ecosystem to its natural state?

  1. Ecological restoration

  2. Habitat fragmentation

  3. Invasive species introduction

  4. Pollution


Correct Option: A
Explanation:

Ecological restoration is the term used to describe the process of restoring a degraded ecosystem to its natural state. This can involve various techniques, such as reforestation, wetland restoration, and the reintroduction of native species, and aims to improve the ecosystem's biodiversity, structure, and function.

Which of the following is NOT a potential consequence of biodiversity loss in urban areas?

  1. Increased risk of flooding

  2. Reduced air quality

  3. Improved water quality

  4. Increased vulnerability to climate change impacts


Correct Option: C
Explanation:

Biodiversity loss in urban areas can have various negative consequences, including increased risk of flooding, reduced air quality, and increased vulnerability to climate change impacts. However, it does not directly lead to improved water quality.

What is the term used to describe the introduction of a species into an ecosystem where it does not naturally occur?

  1. Invasive species introduction

  2. Habitat fragmentation

  3. Pollution

  4. Climate change


Correct Option: A
Explanation:

Invasive species introduction is the term used to describe the introduction of a species into an ecosystem where it does not naturally occur. These species can have negative impacts on native biodiversity by competing for resources, transmitting diseases, or altering the ecosystem's structure and function.

Which of the following is an example of a conservation strategy aimed at preserving biodiversity in urban areas?

  1. Creating green spaces

  2. Reducing pollution

Creating green spaces, reducing pollution, and controlling invasive species are all examples of conservation strategies aimed at preserving biodiversity in urban areas. These strategies help to protect and restore natural habitats, reduce the impacts of human activities, and promote the coexistence of native species.
