Which of the following options is not a correct match for life history variations in various organisms? |
Breeds only once in their life - Pacific salmon fish, bamboo Breeds many times during lifetime - Most birds, mammals Produces a large number of small-sized offspring - Birds Produces a small number of large-sized offspring – Mammals |
Produces a large number of small-sized offspring - Birds |
The correct answer is Option (3) -Produces a large number of small-sized offspring - Birds Under a particular set of selection pressures, organisms evolve towards the most efficient reproductive strategy. Some organisms breed only once in their lifetime (Pacific salmon fish, bamboo) while others breed many times during their lifetime (most birds and mammals). Some produce a large number of small-sized offspring (Oysters, pelagic fishes) while others produce a small number of large-sized offspring (birds, mammals). |
