Question

Quizplus · Accepted Answer

Pollination of crop plants is an ecosystem service as it is a natural process carried out by insects and animals that helps in the reproduction of flowering plants and ensures the production of fruits and seeds, which are important for human consumption. Ecosystem services are the benefits that human beings derive from the natural environment, and pollination is a vital ecosystem service that supports food production and agricultural systems. Therefore, option A is the correct choice.

Options B, C, D, and E are incorrect.

Option B is incorrect because genetically modifying food is not an ecosystem service but a human-made process that involves altering the DNA of organisms to enhance their traits, which increases the yield of crops and improves their resistance to pests, diseases, and environmental stress. Genetic modification involves the use of biotechnology and is not a natural process or benefit that humans derive from the environment.

Option C is incorrect because global warming is not an ecosystem service but a harmful effect of human activities on the environment, leading to an increase in average global temperatures, changes in climate patterns, and disruptions in ecosystems. Global warming is caused by the release of greenhouse gases such as carbon dioxide, methane, and nitrous oxide, which trap heat in the Earth's atmosphere and cause the planet's temperature to rise. Therefore, global warming is a negative impact on ecosystems and the environment, not a service that they provide.

Option D is incorrect because the creation of pollution is not an ecosystem service but a negative impact of human activities on the environment, leading to contamination of air, water, soil, and food with harmful substances that cause health problems, ecological damage, and climate change. Pollution is caused by human activities such as industrialization, transportation, agriculture, and waste disposal, and is not a benefit that ecosystems provide to humans.

Option E is incorrect because erosion is not an ecosystem service but a natural process that involves the removal of soil and sediment from one place to another by water, wind, or ice. Although erosion can be harmful to human activities such as agriculture and construction, it is a natural process that helps to shape landscapes and ecosystems over time. Therefore, erosion is not an ecosystem service but an aspect of the natural environment.
