<span>A) similar evidence collected in multiple experiments by different people

The correct answer is - nitrogen and phosphorus.
The nitrogen and the phosphorus are the two substances that cause most of the eutrophication. It is good for the organisms that live in the water when these two substances are available as they are very important nutrients, but if the optimal amount is surpassed than it can be devastating. When there's high quantities of nitrogen and phosphorus in the water it makes it much more rich in nutrients that it should be. That kind of situation is the best for the algae, which start growing all over the place, quickly covering the water and becoming the dominant life form. As that happens, the organisms that use photosynthesis will die out because the Sun will be blocked, and the algae will also contribute to a big reduction of the oxygen in the water too. The end result being totally destroyed ecosystem that has been overtaken by algae.
The handling and movement of controlled substances is Regulated by the DEA (Drug enforcement administration)
One of the main task of the drug enforcement administration is to combating drug smuggling and use within the United states. Hope this helps
D would be the answer to this question
What would happen is if there was no ecosystem in biodiversity every organism would become effected in such a impactful way. It would Decrease population in animals and Humans
I really hope this helped :)
