Final answer:
Parents of large clutch sizes are at a higher risk for mortality due to factors such as competition for resources, vulnerability to predators, and the physical strain of supporting a growing fetus.
Step-by-step explanation:
<p>Parents of large clutch sizes are at a higher risk for mortality due to a combination of factors. Organisms that invest in long-term parental care and have many offspring face a greater risk of rapid population increase, which can lead to competition for resources and increased vulnerability to predators. Additionally, supporting a growing fetus is physically draining and risky for the mother, making her more susceptible to predation and less able to escape from danger.</p>
