You need to be a bit more specific!!
It would be B.) ospreys; decomposers
Since ospreys eat nothing but fish, if all of the trout died from a disease, the ospreys wouldn't have anything to eat because all of the fish are dead. This results in a loss of energy for the ospreys.
However, decomposers would gain more energy because they gain their energy from dead creatures, in this case, it would be the trout.
If there is a leakage of the manure pond into the near by river, the growth the nitrates and phosphates in the leak causes an overgrowth of algae leading to eutrophication.
<h3>What is a manure?</h3>
A manure is that which is used to improve the fertility of the soil. It is composed of the nutrients that are required by the soil. We know that each pig produces 30 liters of manure each day, and the average feedlot holds 900 pigs. Hence, each day, 30 * 900 = 27000 litres of manure is produced.
Within a period of 30 days, a total of 27000 litres of manure * 30 = 810,000 litres of manure is produced. If there is a leakage of the manure pond into the near by river, the growth the nitrates and phosphates in the leak causes an overgrowth of algae leading to eutrophication.
