Moosehead Lake in Maine is a beautiful lake, spanning 74,890 acres with a maximum depth of 246 feet. The most sought-after fish to be found in Moosehead Lake are: Landlocked salmon, lake trout, brook trout, and burbot. According to Tim Obrey, a regional fisheries biologist with the Maine Department of Inland Fisheries and Wildlife, the fishing at Moosehead declined from phenomenal to just "really good" during the late 1980s, but has rebounded due to careful management. This table shows the populations of three major fish in Moosehead Lake over a 30 year period. Moosehead Lake was illegally stocked with smallmouth bass in 1970. Fish Populations in Moosehead Lake Year Smallmouth Bass Salmon Lake Trout

Smelts are the primary food source for lake trout and salmon in Moosehead. In the late 1980s, we documented a dramatic increase in the abundance of wild lake trout in Moosehead Lake. Swelling lake trout numbers taxed the forage base and the smelt population took a dive. What would be appropriate action for Wildlife Management to make to correct the problem? Choose ALL that apply.

B) One hundred small, one-hectare size areas should be conserved
C) Native species should be maintained or planted within the greenspace to promote biodiversity.
D) Exotic species should be cultivated and planted to increase biodiversity in the protected greenspace.
E) The majority of the secondary consumers should be removed from the greenspaces to promote an increase in lower levels of the food chain.

Answer 1

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 burbot

Smelts, 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 2

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.

What is insulin?

A kind of insulin used to control diabetes is glargine insulin. It falls within the category of long-acting basal insulin. In order to meet the body's regular insulin requirements between meals and during fasting periods, basal insulins offer a gradual and consistent release of insulin over a lengthy period of time.

Glargine insulin maintains blood sugar control for a considerable period of time, usually up to 24 hours, with a generally steady and protracted action.

Explanation: because I had the same question too on acellus and got a right

Photosynthesis makes use of light energy while chemosynthesis is the main source of energy capture where light energy is not available.

What is photosynthesis?

It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy  through the process of cellular respiration.

Some of the energy which is converted  is stored in molecules of carbohydrates like sugar and starches  which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis  are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.

The process begins with proteins absorbing light energy  which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.
