Which of the following correctly describes the disruption of an ecosystem service by an anthropogenic activity?
ehidna [41]

Answer:

The correct answer is "Provisioning services are disrupted by increased combustion of fossil fuels, which leads to an increase in air pollution".

Explanation:

The ecosystem provides several services that if used with responsibility, could be sustained by the nature. Unfortunately, disruption of an ecosystem service could happen by an anthropogenic activity, which are the activities that humans perform. One example is the disruption of provisioning services by increased combustion of fossil fuels, which leads to an increase in air pollution. The ecosystem provides clean air that gives oxygen for people and animals to breath, however high combustion of fossil fuels could disrupt this service.
