Answer:
A. Puffins receive energy from herring, herring receive energy from krill, and krill receive energy from phytoplankton.
Explanation:
A food chain represents the unidirectional network or path of the flow of energy and the matter in an ecosystem.
The aquatic food chain begins from the small or microscopic organisms called phytoplankton which is autotrophic therefore are considered the producers.
The phytoplanktons are eaten by a variety of other organisms in which the krills which live in the deep sea feeds on these phytoplanktons. The krills are the primary consumers who are eaten by small fish like herring which acts as secondary consumers. These herring are then eaten by the bird-like puffins and large fish which acts as tertiary consumers.
Thus, Option-A is the correct answer.
Answer:
D. Specialist Species
<h2>
What is the advantage for species to be specialists, and how can they survive in the presence of opportunistic/generalist species?</h2>
In the setting of specialized habitats or unique situations, specialized species exist. When those conditions and surroundings change, they must adapt or go extinct, thus they must survive while they still exist.
When compared to generalists, they have the benefit of efficiency, which increases the likelihood of survival and, hence, reproduction within certain settings or situations. The generalists, on the other hand, have the benefit of being able to survive in a larger variety of circumstances and have a higher probability of doing so.
Cactuses, which are plants adapted to dry environments, are an example of specialization. More generalist plant species would typically outcompete cacti in most habitats on Earth, but very few of such species could endure the harsh conditions of a desert.
Extreme environmental conditions, competition for limited resources, and "evolutionary arms races" are some of the pressures that cause specialization. Cheetahs sprint quickly both because their prey moves quickly and because quicker cheetahs will be more effective hunters and more likely to procreate. The advantage of specialization is clear when seen from the standpoint of catching the next meal on a daily basis.
My key argument is that specialization's benefits must always be viewed in the context of the environment that generated the selective pressure that resulted in specialization. Although experts are specialists because they must be, their specializations put them in danger.
it would be the area with frequent thunderstorms would be the answer cause more rainfall, more water erodes rock after the water has been there for a while it breaks down the sediment just like taking a bath or swimming the water makes your skin wrinkley . so the area with frequent thunderstorms is the answer.
An ionic bond occurs between two oppositely charged ions, which means that it occurs between D. a positive and negative ion.
The main product is GLUCOSE and the other would be Oxygen so the answer is C.
