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.

Hoochie [10]

Organize the lengths below from shortest to longest.

 

28 dm ,629,000 mm ,1.2 km, 30,277 cm

To answer this, all values should be converted in the same unit just like in km

28 dm = 0.0028 km

629,000 mm = 0.629 km

1.2 km

30,277 cm = 0.30277 km

So the order is 28 dm, 30,277 cm , 629,000 mm and 1.2 km
