Ah, almost but your understanding of feedback is backwards.

Negative feedback means the output is fed back and inhibits further growth in the output, stable

Positive feedback means the output is fed back and INCREASES growth in the output, UNSTABLE. This is what they are talking about, more leads to much more

The correct answer is c. positive feedback system.

In this example, as the oceans warm, they become less capable of absorbing carbon dioxide, resulting in less carbon dioxide being soluble in them. This leads to an increase in the amount of carbon dioxide in the atmosphere, which in turn contributes to further warming of the atmosphere. This process creates a positive feedback loop, where the initial warming leads to more warming, amplifying the effects.

Negative feedback systems, on the other hand, work to stabilize or counteract changes within a system. Positive feedback systems, like the one described above, intensify or amplify changes.

Therefore, the correct answer is c. positive feedback system.

To determine the correct answer, let's break down the options and analyze the scenario you provided.

a. Model of a system showing a paradigm shift.
A paradigm shift refers to a major change or shift in thinking or understanding. While the scenario you described involves changes in the relationship between warming oceans, carbon dioxide solubility, and atmospheric warming, it does not necessarily involve a fundamental shift in scientific understanding or a change in the prevailing paradigm. Therefore, option a is not the correct answer.

b. Negative feedback system
In a negative feedback system, a change or perturbation in a system leads to a response that counteracts or reduces the effect of that change. In the given scenario, warming oceans causing less carbon dioxide solubility results in more carbon dioxide remaining in the atmosphere, which in turn contributes to increased warming. This feedback loop amplifies the initial change, rather than counteracting it. Therefore, option b is not the correct answer.

c. Positive feedback system
In a positive feedback system, a change or perturbation in a system leads to a response that reinforces or amplifies the effect of that change. In the scenario you described, the initial warming of the oceans reduces the solubility of carbon dioxide, which leads to more carbon dioxide in the atmosphere, causing increased warming. This feedback loop amplifies the initial change. Therefore, option c is the correct answer.

d. Scientific principle of sustainability
The scientific principle of sustainability refers to the practice of utilizing resources in a way that does not deplete or damage the environment, ensuring their availability for future generations. The scenario you provided describes the mechanism of how oceans warming and increased atmospheric carbon dioxide contribute to further warming, but it does not relate directly to the concept of sustainability. Therefore, option d is not the correct answer.

e. Natural law
Natural laws are fundamental principles or rules that govern the natural world. While the scenario you described represents a natural phenomenon, it does not encompass a universally accepted and well-established principle or rule like those typically classified as natural laws. Therefore, option e is not the correct answer.

Based on the analysis, the correct answer is c. positive feedback system.
