Yet the prey can maintain their numbers by growing fast, reproducing fast and eating not just the next victim below them in the food web but also algae.
他们仅仅通过年长雌性更有可能生出雄性的子代，就确确实实的证明了随着雌性年龄的增加他们的繁殖风险也随之增加。
What they do prove is that the reproductive risk to a female increases as she gets older, merely because she is more likely to give birth to a male.
