When one of the trophic web links disappears, it affects the whole chain. In management programs it is important to consider these consequences to keep the whole ecosystem equilibrium. In the exposed situation, Native species should be maintained or planted within the greenspace to promote biodiversity and The majority of the secondary consumers should be removed from the greenspaces to promote an increase in lower levels of the food chain.
--------------------------------------
The trophic chain is the energy transference process that involves different organisms, from autotroph or producers, to the consumers or decomposers.
The disappearance of one link affects the whole system. The direct superior link does not have enough food supply, while the immediately anterior link is beneficiated for not being eaten by its predator. And finally, as this last link will overgrow, it will consume greater quantities of its food, causing a decrease in its anterior link. Top-down control refers to scenarios where superior predators control the structure and dynamic of an ecosystem.
It is necessary and significant to consider these modifications in the whole ecosystem while planning management actions to keep an equilibrium.
In the exposed example we know that the most wanted species are
Landlocked salmon, lake trout → which increased its population size sharply over the last yearsbrook trout, and burbotSmelts, which are the primary food source for lake trout and salmon, decreased in population size significantly.
Finally we know that smallmouth bass was introduced in 1970.
This information suggests that the decrease in smelts' population is due to the predation of the species by the lake trout, which population increased sharply in size. The change on smelts' population size, might affect the blook trout and salmon populations, that also feed on semelts, and might also affect other species occupying inferior levels.
When implementing a management program, it would be necessary to promote biodiversity by growing native species in greenspaces and ensure their survival and reproductive succes. In the exposed case, it is necessary to preserve smelts' population, so it would be also necessary to remove from these green spaces the secondary consumers -trouts and salmon- that feed on them, to ensure the smelts' population growth and recovery.

Answer:
The Answer is A, C, and D
Explanation:
Wildlife management reacted to the increase in trout and depletion of smelt by liberalizing bag limits on lake trout and allowing harvest of smaller fish. We also severely reduced the salmon stocking rates. Salmon and trout populations had to be controlled until smelt could rebound.
11.Oxides of sulfur and nitrogen that combine
with water vapor cause
a. hydrolysis.
b. acid rain.
c. mechanical weathering.
d. carbonation
Answer:
[tex]\huge\boxed{\sf Acid \ Rain}[/tex]
Explanation:
Oxides of sulfur and nitrogen combine with air and water vapors to produce more acidic substances (low pH) and consequently, acid rain is produced which can be of great damage for the living and non-living things on the Earth.
