Which of the following best describes an opportunistic species?

An opportunistic species is characterized by its ability to thrive in unstable or unpredictable environments, which often involves producing a large number of offspring with minimal parental care. This reproductive strategy allows them to quickly exploit available resources and take advantage of temporary opportunities, such as increased food or reduced competition. By producing many offspring, these species maximize their chances of survival and reproduction, even if many of the young do not survive to adulthood.

This approach contrasts with other reproductive strategies, such as those seen in organisms that exhibit stable populations over time, have longer life spans, or maintain a consistent ecological role. Species with stable populations typically involve more parental investment and lower offspring numbers to ensure survival, while those with longer lifespans often balance their reproduction with care for a few young. Species that maintain a consistent ecological role are generally more specialized and less adaptable to sudden changes in their environment. Thus, the key traits of an opportunistic species—high reproductive output and low parental care—best describe option B.
