SSC Selection Post 2024 PYQ — Question 49

The correct answer is option 1 i.e. species possessing relatively stable populations and which tend to produce relatively low numbers of offspring.

• K-selected species are characterized by species possessing relatively stable populations and which tend to produce relatively low numbers of offspring.

• K-selected species typically have long gestation periods that can span several months, mature slowly, and often live for many years. Because of their slow development, they usually receive prolonged parental care. These species are commonly found in stable ecosystems, such as mature or climax forests that emerge in the final stages of ecological succession.

• Their population growth generally follows the logistic growth model, which reflects how population size levels off as resources become limited.

  • $\frac{\triangle N}{\triangle t}= rN\left (\frac{K-N}{K} \right )$
