Question

In order to maximise their reproductive fitness, organisms evolve towards efficient reproductive strategy. In the given options, identify the correct reproductive strategy/strategies observed in the nature.

• A. Oysters produces small number of large-sized offsprings
• B. Pacific salmon fish breed only once in their life time
• C. Both (a) and (c)
• D. Pelagic fishes produce a large number of small-sized offspring

Answer 1

The correct option is C Both (a) and (c)

Based on the particular set of selection pressures faced by organisms in a population, the organisms evolve towards the most efficent reproductive strategy. Thus leading to a population that maximise their reproductive fitness. Certain examples of most efficient reproductive stratgey are as follows:
1. Organisms like Pacific salmon fish and bamboo, breed once in their lifetime
2. Organisms like Oysters and Pelagic fishes, produce a large number of small-sized offspring.
3. Organisms like birds and mammals produce a small number of large-sized offspring.
Thus option (a) and (c) are correct reproductive strategies observed in the nature.
