Which human activity is a major contributor to habitat destruction and fragmentation, leading to biodiversity loss?

  1. Sustainable agriculture

  2. Urbanization

  3. Reforestation

  4. Wildlife conservation


Correct Option: B
Explanation:

Urbanization involves the conversion of natural habitats into built-up areas, leading to habitat loss and fragmentation, which negatively impacts biodiversity.

What is the primary cause of overexploitation of natural resources, resulting in biodiversity decline?

  1. Climate change

  2. Habitat destruction

  3. Unsustainable consumption

  4. Pollution


Correct Option: C
Explanation:

Unsustainable consumption, particularly of natural resources, drives the overexploitation of species, leading to their population decline and potential extinction.

Which human activity is responsible for introducing invasive species to new environments, causing ecological disruption and biodiversity loss?

  1. Ecotourism

  2. Habitat restoration

  3. International trade

  4. Conservation biology


Correct Option: C
Explanation:

International trade, particularly in live animals and plants, can unintentionally introduce invasive species to new environments, where they can outcompete native species and disrupt ecosystems.

What is the primary driver of climate change, which poses a significant threat to biodiversity?

  1. Renewable energy development

  2. Sustainable agriculture

  3. Fossil fuel burning

  4. Deforestation


Correct Option: C
Explanation:

Fossil fuel burning releases greenhouse gases into the atmosphere, contributing to climate change. Climate change impacts biodiversity through altered habitats, species' distributions, and ecological interactions.

Which human activity is a major source of pollution, including plastic waste, that harms marine ecosystems and biodiversity?

  1. Organic farming

  2. Sustainable fishing

  3. Industrial manufacturing

  4. Renewable energy production


Correct Option: C
Explanation:

Industrial manufacturing processes often generate pollutants, including plastic waste, which can end up in marine environments, harming marine life and disrupting ecosystems.

What is the term used to describe the process of converting natural habitats into agricultural land, leading to biodiversity loss?

  1. Reforestation

  2. Habitat restoration

  3. Agroforestry

  4. Land conversion


Correct Option: D
Explanation:

Land conversion involves the transformation of natural habitats, such as forests or wetlands, into agricultural land, resulting in habitat loss and biodiversity decline.

Which human activity is a major contributor to water pollution, leading to degradation of aquatic ecosystems and biodiversity loss?

  1. Water conservation

  2. Sustainable agriculture

  3. Industrial waste disposal

  4. Rainwater harvesting


Correct Option: C
Explanation:

Industrial waste disposal, particularly the discharge of untreated or inadequately treated wastewater, contributes to water pollution, harming aquatic ecosystems and the biodiversity they support.

What is the term used to describe the introduction of non-native species to an environment, often leading to ecological disruption and biodiversity loss?

  1. Endangered species conservation

  2. Habitat restoration

  3. Invasive species introduction

  4. Biodiversity management


Correct Option: C
Explanation:

Invasive species introduction involves the intentional or unintentional introduction of non-native species to an environment, where they can outcompete native species and disrupt ecological balance.

Which human activity is a major contributor to air pollution, leading to respiratory problems and biodiversity loss?

  1. Renewable energy production

  2. Sustainable transportation

  3. Industrial emissions

  4. Forest conservation


Correct Option: C
Explanation:

Industrial emissions, particularly the release of harmful gases and particles into the atmosphere, contribute to air pollution, affecting human health and biodiversity.

What is the term used to describe the process of restoring degraded ecosystems to their natural state, promoting biodiversity recovery?

  1. Habitat destruction

  2. Biodiversity conservation

  3. Habitat restoration

  4. Ecosystem management


Correct Option: C
Explanation:

Habitat restoration involves the active restoration of degraded ecosystems to their natural state, aiming to improve biodiversity and ecological function.

Which human activity is a major contributor to noise pollution, leading to disruption of wildlife behavior and biodiversity loss?

  1. Sustainable tourism

  2. Renewable energy production

  3. Industrial development

  4. Wildlife conservation


Correct Option: C
Explanation:

Industrial development, particularly the operation of heavy machinery and construction activities, can generate noise pollution, affecting wildlife behavior and biodiversity.

What is the term used to describe the process of managing and conserving biodiversity, including the protection of threatened species and their habitats?

  1. Habitat destruction

  2. Biodiversity conservation

  3. Ecosystem management

  4. Sustainable development


Correct Option: B
Explanation:

Biodiversity conservation involves the management and protection of biodiversity, including threatened species and their habitats, to ensure their long-term survival.

Which human activity is a major contributor to light pollution, leading to disruption of wildlife behavior and biodiversity loss?

  1. Sustainable agriculture

  2. Renewable energy production

  3. Urban development

  4. Wildlife conservation


Correct Option: C
Explanation:

Urban development, particularly the excessive use of artificial lighting, can lead to light pollution, affecting wildlife behavior and biodiversity.

What is the term used to describe the process of reducing or eliminating human activities that negatively impact biodiversity, promoting its conservation?

  1. Habitat destruction

  2. Biodiversity conservation

  3. Mitigation

  4. Sustainable development


Correct Option: C
Explanation:

Mitigation involves reducing or eliminating human activities that negatively impact biodiversity, aiming to minimize their effects and promote conservation.

Which human activity is a major contributor to soil pollution, leading to degradation of ecosystems and biodiversity loss?

  1. Sustainable agriculture

  2. Renewable energy production

  3. Industrial waste disposal

  4. Forest conservation


Correct Option: C
Explanation:

Industrial waste disposal, particularly the improper disposal of hazardous chemicals and heavy metals, can lead to soil pollution, affecting ecosystems and biodiversity.
