If this question has the same illustration as to the other ones posted before, well, here is a brief explanation why the <span>population of trout might increase if the population of frogs decreased.
Trout is a fish living in freshwater. When trout lay eggs, eventually adult frogs (amphibians) will take them as their food. If there are frogs living in the freshwater where trouts live, then trout wont be able to breed fingerlings.Therefore, if the population of frogs decrease, population of trouts increase.</span>
The gravitational force would increase, as the mass is increasing.
Latex balloons is the answer.
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.
