ANSWER:

The effects of increasing or decreasing the nutrient levels in an aquatic food webs is described in the explanation.

Explanation:

If the nutrient levels in an aquatic food web increase moderately then it will result in increased production of the primary producers and the consumers.

But if the nutrient levels are increased excessively, like in eutrophication, then the increased level of nutrients will result in overproduction of the consumers like fishes, etc. Hence, there will be a scarcity of resources like oxygen in the water to support them and this will lead to a decline in biodiversity of the aquatic food web.

If the nutrient levels are decreased, then there will be competition for resources among the species which will ultimately lead to the decline of some species from the aquatic food web.

One reasonable plan would be to wear a face mask or surgical mask. Take note that your surgical mask contains two sides – the white side and the blue side. Since the main purpose of your mask usage is to prevent yourself from inhaling too much bad air, the blue side of the mask should be the one touching your skin. This is because the white side of your mask helps you prevent from coming in contact with toxins that may come from the smog.

1. One reason is extinctions happen because of some kind of change in the environment where a life form lives. While some species can adapt to the changes, others die, and if enough die, the species becomes extinct. These are some of the biggest factors in the extinctions of particular species. 2. Contaminants in the environment, such as pesticides.
