Answer
Three life history traits:
1) Age during first reproduction
2) Reproductive lifespan
3) Number and size of offspring
Work Step by Step
Examples:
1) Some turtles reproduce at around 30 years old, while salmon begin reproducing at just 4 years.
2) Humans reach sexual maturity in the teenage years and are able to reproduce for several decades. Certain cetaceans and insects must reproduce within a single year in their lives.
3) Rhinoceros with single calf vs turtles with hundreds of eggs.
Organisms always demonstrate tradeoffs in terms of life histories: Those who produce few offspring are able to offer more intensive care and those who produce many offspring cannot provide as much.
