Nutrient Cycles Why do the nutrients on the Earth need to be cycled? The Earth is considered a closed system. This means that there is little or no input of new materials from outside the system.

Nutrient Cycles Organics = H and C, often O and N (proteins, fats, sugars) Inorganics – not containing C and H Nutrients can be in the biotic environment or abiotic environment.

The Carbon Cycle Plants make carbohydrates through a process known as photosynthesis. 6CO2 + 6H2O + E  C6H12O6 + 6O2 Capture of carbon from atmosphere Carbon is returned to the atmosphere via cellular respiration. C6H12O6 + 6O2  6CO2 + 6H2O + E

The Nitrogen Cycle Nitrogen is also very important and it will also circulate between the biotic and abiotic parts of the environment. Proteins and DNA Fertilizers contain N, P and K to facilitate growth If there is no fertilizer then how does the plant acquire N?

Agriculture and Nutrient Cycles Phosphate Accumulation Algae growth = algal bloom Bacteria break down algae and use oxygen to do so Fish and animals die Problems become worse
