What services are provided by natural, well-functioning ecosystems

Increase in ambient global temperatures.

Recyling energy to be used again

Regulation of oxygen and carbon dioxide levels

An increase of erosion and siltation along waterways

Explanation:

Nutrient cycling

Decomposition of dead organisms

Dispersal of pollen and seeds

Purification of air and water

Reduction of the severity of droughts and floods

Pollination of crops and natural vegetation

Sources of medicines

Regulation of oxygen and carbon dioxide levels
