Question

1. must every member of a particular species (one kind of organism) be able to reproduce in order for the species to survive? explain why or why not.

Explanation:

A species survives if enough members reproduce to sustain the population. Some individuals (e.g., sterile organisms like worker bees, infertile animals) can't reproduce, but as long as a sufficient number of reproductively - capable members produce offspring, the species can persist. The key is the overall reproductive output of the population, not every single individual's ability to reproduce.

Answer:

No, every member of a particular species does not need to be able to reproduce for the species to survive. Because a species' survival depends on the population's overall reproductive success. There are individuals within a species (such as sterile worker bees or infertile members of a species) that cannot reproduce, but as long as there are enough reproductively - capable members that can produce offspring to maintain the population size (and allow for evolution through processes like natural selection), the species can survive.
