Which of the following is a major threat to biodiversity?
Explanation: The correct answer is D) All of the above. Habitat destruction, climate change, and pollution are major threats to biodiversity. Habitat destruction, such as deforestation and urbanization, leads to the loss of species' habitats. Climate change affects ecosystems and species' ability to adapt to changing conditions. Pollution, including air and water pollution, can directly harm species and disrupt ecosystems.
Which of the following contributes to habitat destruction?
Explanation: The correct answer is D) All of the above. Deforestation, land conversion for agriculture, and urbanization are all activities that contribute to habitat destruction. Deforestation involves the clearing of forests for timber, agriculture, or urban expansion. Land conversion for agriculture involves transforming natural habitats into farmland. Urbanization refers to the expansion of cities and towns into surrounding natural areas, resulting in the loss of habitats for many species.
How does climate change impact biodiversity?
Explanation: The correct answer is D) All of the above. Climate change has multiple impacts on biodiversity. It can alter ecosystems and disrupt species' habitats through changes in temperature, precipitation patterns, and sea-level rise. Climate change also affects species' distribution and migration patterns as they respond to changing environmental conditions. These changes increase the risk of species extinction, as some species may struggle to adapt or find suitable habitats.
What is a major source of pollution affecting biodiversity?
Explanation: The correct answer is D) All of the above. Pollution affecting biodiversity can come from various sources. Air pollution, such as emissions from industrial processes and vehicles, can have harmful effects on both terrestrial and aquatic ecosystems. Water pollution, caused by chemical runoff, sewage, and industrial waste, can contaminate water bodies and harm aquatic life. Chemical pollution from pesticides, herbicides, and other toxic substances can also negatively impact biodiversity.
How can threats to biodiversity be addressed?
Explanation: The correct answer is D) All of the above. Addressing threats to biodiversity requires a comprehensive approach. Conservation and restoration of habitats help protect and preserve the homes of many species. The sustainable use of natural resources ensures that ecosystems can continue to provide essential services without depletion. Adoption of biodiversity-friendly practices in agriculture, forestry, and other sectors minimizes negative impacts on biodiversity while meeting human needs.
