Question

A semelparous species can be defined as

• A. A species that reproduces multiple times in its life
• B. A species that does not reproduce at all
• C. The new species formed by the process of speciation
• D. The species that reproduce 3 times a year
• E. A species that reproduces only once in its life and then die

Answer 1

The correct option is E A species that reproduces only once in its life and then die

Semelparous strategy occurs in organisms who reproduce once in a life time. These types of organisms have one life cycle because they have limited source of energy for carrying out all their life processes. Hence persistently low energy levels in the environment lead the organism to have only one reproductive cycle in the life.
