Your neighbor faithfully applies fertilizer to his lawn to ensure beautiful healthy green grass. explain how your neighbor’s fertilizing habit affects at least one nutrient cycle

Explanation:

Nutrient cycle is the exchange of organic and inorganic matter between physical environment and living organisms .

Hence , when the neighbor is applying fertilizers, then he is giving essential providing macro nutrients (phosphorous, nitrogen and potassium) to the soil. But soil will have both micro and macro nutrients in balance. Excess macronutrients will reduce micronutrients availability , as plant may not be using all the nutrients supplied by the neighbor . This will cause the accumulation of nitrogen in the soil thus affecting the nitrogen cycle (nitrogen cycle is one of the Earth's biogeochemical cycles). Plants will get nitrogen from soil and bacteria will convert it to a usable form , but readily available excess nitrogen will allow the growth of weeds, and washing of these nutrients will create eutrophication situation. In usual cases plants absorbs nitrogen in the form of nitrates  and bacterial also converts ammonium into nitrates, the denitrifying bacteria converts this nitrate to nitrites and nitrogen gas. The excessive availability of nitrogen from fertilizer will disturb the balance of nitrogen available in the soil .

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
