Which of the following is a close example of regulating ecosystem services?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Removal of CO2 from atmosphere and release of O2 by plants
Regulating services are the benefits obtained from the regulation of ecosystem processes — climate regulation, air purification, water purification, flood control, pollination and disease control. Photosynthesis, which draws down carbon dioxide and releases oxygen, regulates the composition of the atmosphere and the climate, so it belongs to this class.
Genetic resources and raw materials such as organic matter and fodder are provisioning services, while cultural diversity is a cultural service.
