Which of the following statements about nutrient inputs and eutrophication is FALSE? O Fossil fuel combustion (e.g. burning gasoline, coal) releases nitrogen which contributes to eutrophication The production of chemical farm fertilizers through industrial fixation of N, is a major source of bioavailable nitrogen and cause of eutrophication O The mining of phosphate rock for fertilizers is a major source of bioavailable phosphorus and cause of eutrophication O Eutrophication can cause oxygen depletion in aquatic systems by increasing the growth of algae which consume a lot of oxygen The production of livestock at large-scale (which generates a lot of manure) can be a cause of eutrophication

Terrestrial Ecosystem

An ecosystem is a collection of interconnected communities. It includes both living and non-living elements of specific strata. The terrestrial ecosystem is solely related to the ecosystem present on the land and covers 25 to 30% of the total earth’s surface area.
