Problem 1: The global nitrogen cycle is crucial for maintaining the balance of nitrogen in terrestrial and aquatic ecosystems. Human activities, particularly the industrial synthesis of ammonia for fertilizers and the cultivation of nitrogen-fixing crops, have significantly altered the nitrogen fluxes in the environment. Consider the following data to solve the problems below: • Natural nitrogen fixation (by lightning and biological fixation in soils and water) globally adds approximately 100-200 Tg (teragrams) of nitrogen to terrestrial ecosystems annually. • Industrial nitrogen fixation for fertilizers and other chemicals adds about 120 Tg of nitrogen per year. • The cultivation of nitrogen-fixing crops contributes an additional 40 Tg of nitrogen per year to terrestrial ecosystems. • The estimated total denitrification process, which converts nitrates back to N2 gas, removes about 210 Tg of nitrogen from terrestrial and aquatic ecosystems annually. Questions: • Calculate the total annual addition of nitrogen to terrestrial ecosystems from natural and human sources. • Determine the net increase or decrease in nitrogen added to terrestrial ecosystems when considering the denitrification process. • Discuss the potential ecological impacts of the net increase or decrease in nitrogen on terrestrial and aquatic ecosystems. • Discuss strategies that could be implemented to mitigate the negative impacts of increased nitrogen in ecosystems.

Mike wishes to buy 500 bushels of wheat (asset) in 2 weeks. The price of a bushel of wheat is $9.50 today (time = t). the spot price of the asset is s(t) = $9.50 * 500. Denote maturity as T and the price of the asset at time T, S(T) is unknown. What price, F should Mike pay if the valuation of the forward contract is arbitrage. Free. Note: Mike can earn 2% annually on deposits made in the local bank. (For purposes of computation a year has 50 weeks so T-t = 2* 1/50 = 1/25).
