Hello, I need this done in the next 30min if possible. thanks.

1 Fertilizing Fish When farmers fertilize their elds, the nitrogen from the fertilizer can get washed into streams which then feed into larger rivers. This \"runoff\" can cause damage to ecosystems and reduce the number of sh that can be caught by shermen farther downstream. Who are the producers of fertilizer? Who are the consumers of fertilizer? |1Who are the third parties affected by the externality? The graph below shows the market for fertilizer where P = 2 + 0.5(25 and P = 20 Q5. The marginal external cost of fertilizer = Q. This means, for example, if 3 units of fertilizer are used then the last unit of fertilizer causes shermen to suffer a $3 loss...however, they are worse off by $1 from the rst unit and $2 from the second unit as well for a total welfare loss of $6. What is the equation for your new curve? Label the curves on the graph, indicating if they're S or D, private or social. Draw 35 label a new curve demonstrating the externality. $ funit Fertilizer 25 20 15 10 5 5 10 15 20 25Units of Fertilizer PM: , ka: Psoc .
