Verified step by step guidance1
Understand the concept of semelparity: Semelparity is a reproductive strategy where an organism reproduces only once in its lifetime, producing many offspring, and then typically dies shortly after.
Analyze the example of the agave plant: The agave plant stores energy throughout its life and then releases many seeds before dying. This fits the definition of semelparity as it reproduces once and then dies.
Consider the example of fruit flies: Fruit flies can lay hundreds of eggs per week once they reach maturity. This is an example of iteroparity, where organisms reproduce multiple times over their lifespan.
Evaluate the example of a female labrador: A female labrador having puppies in different years is also an example of iteroparity, as it involves multiple reproductive events over time.
Conclude which example fits semelparity: Based on the definitions and examples, the agave plant is the correct example of semelparity, as it reproduces once and then dies.
