Final answer:
The idealized survivorship curve being described is type III survivorship curve. Organisms that exhibit a type III survivorship curve produce large numbers of offspring, but provide very little or no care for them.
Step-by-step explanation:
The idealized survivorship curve being described is type III survivorship curve. In type III survivorship curves, the highest mortality occurs at early ages, with much lower mortality rates for organisms that make it to advanced years. Organisms that exhibit a type III survivorship curve typically produce large numbers of offspring, but provide very little or no care for them.
