Hint: The disappearance of the species may directly impact other species which depend on it for survival. The biological system can't continue a boundless measure of creatures and the deer will presently go after food and water assets with one another.

Complete answer:
Prevailing species are the most plentiful species in a network, applying a solid impact over the event and circulation of different species. Interestingly they have impacts on networks that far surpass their wealth. In other words, the significance of would not be anticipated dependent on their event in an environment. Predominant the flavors impact the presence and plenitude of different life forms through their taking care of connections.

Taking care of connections — eating or being eaten — are called trophic collaborations. Furthermore, a few living beings, called establishment species, apply impact on a network not through their trophic cooperation, yet by causing physical changes in nature. These life forms adjust nature through their conduct or their enormous aggregate biomass. Establishment species may likewise be predominant species.

Community structure: Predators can increase diversity in communities by preying on competitive dominant or by lessening customer pressure on establishment species. For instance, in rough intertidal frameworks of the Pacific Northwestern US, mussels, barnacles, and ocean growth require a hard substrate to develop on, and they seek space on the rocks.

Hence the correct answer is OPTION(B)
