Which one or more of the following options represent(s) life history trade-offs?
Show Hint
- Egg size versus clutch size
- Growth versus age at sexual maturation
- Mate choice versus offspring quality
- Survival versus reproduction
The Correct Option is A, B, D
Solution and Explanation
Life history trade-offs refer to the balancing act that organisms must perform between different biological processes such as reproduction, survival, and growth. These trade-offs are crucial for understanding evolutionary strategies.
Step 2: Explanation of each option.
(A) Egg size versus clutch size is a classic trade-off, where producing fewer, larger eggs may be beneficial in terms of offspring survival, but fewer offspring are produced.
(B) Growth versus age at sexual maturation is another trade-off. Faster growth may delay reproduction, while early reproduction may limit growth.
(C) Mate choice versus offspring quality is not a direct trade-off in life history, though it may influence evolutionary outcomes, it is not typically seen as a fundamental life history trade-off.
(D) Survival versus reproduction is a well-known trade-off in evolutionary biology, where resources allocated to reproduction may reduce survival, and vice versa.
Step 3: Conclusion.
The correct answers are (A), (B), and (D) because these are well-documented life history trade-offs.
