Question

Which of the following is correct for r-selected species ?

• A. Large number of progeny with small size
• B. Large number of progeny with large size
• C. Small number of progeny with small size
• D. Small number of progeny with large size

Answer 1

The Correct Option is A

Option 1: Large number of progeny with small size

Explanation:

r-selected species are characterized by traits that favor rapid reproduction. These species invest little energy in raising individual offspring and typically produce a large number of offspring with smaller sizes. This reproductive strategy helps the species take advantage of environments where resources are abundant but competition and predation are high.

Characteristics of r-selected species:

• They produce a large number of offspring.
• The offspring are typically small in size.
• They have a short lifespan and rapid growth rate.
• They invest less parental care in their young.
• Examples include many insects, fish, and weeds.

Conclusion:

The correct answer is Option 1: Large number of progeny with small size, as this is characteristic of r-selected species.
