Lizards that produce many eggs often have a shorter lifespan than those who produce fewer eggs. Which one of the terms below describes the relationship between the number of eggs and lifespan?
Show Hint
- Compensatory growth
- Frequency dependent selection
- Biomagnification
- Life-history tradeoff
The Correct Option is D
Solution and Explanation
Step 1: Understanding Life-history tradeoff.
A life-history tradeoff refers to the balancing of different traits that affect an organism's survival and reproduction. In this case, the tradeoff between producing many eggs (which may reduce lifespan) and producing fewer eggs (which may allow for a longer lifespan) is an example of such a tradeoff.
Step 2: Explanation of the other options.
Compensatory growth involves rapid growth to make up for previous stunting.
Frequency dependent selection is when the fitness of a phenotype depends on its frequency in the population.
Biomagnification refers to the increase in concentration of toxins up the food chain.
