Question:
As an efficient reproductive strategy under environmental selection pressure, some organisms like _________ and _________ produce a small number of large-sized offspring
As an efficient reproductive strategy under environmental selection pressure, some organisms like _________ and _________ produce a small number of large-sized offspring
Show Hint
Species that give heavy parental care produce a small number of large offspring.
Updated On: Nov 12, 2026
- oysters and pelagic fishes
- birds and mammals
- clown fish and sea anemone
- zebra mussels and chlamydomonas
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding the Concept
Life-history strategies differ. Some species produce a huge number of tiny offspring with no care.
Step 2: Two strategies
Oysters and pelagic fishes produce many small offspring. Birds and mammals produce few large offspring and invest heavily in parental care.
Step 3: Conclusion
The pair that produces a small number of large-sized offspring is birds and mammals.
Final Answer:
Birds and mammals produce a small number of large offspring. \[ \boxed{\text{(B) }\text{birds and mammals}} \]
