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.
Dead mustard plants disintegrate into the soil And the worms in the soil see it and are like woah man let’s fricking rave! So these worms rave until the riff of dawn and the air gets so dense it just turns into nitrogen. The rave vibes were so lit that the nitrogen had this gold ora to it. The worms gathered it all and in a way, molded it into a seedling. They were like “ we gonna name it marigold cuz we had a pretty merry good time”. So yea science is wild isn’t it?
Nectar attracts bees and other pollinators to the flowers and then the pollen gets stuck to the pollinator. Once the pollinator goes to a different flower, the pollen that was originally on the pollinator goes onto the present flower. That is how nectar helps flowers become pollinated
