NEET BIOLOGY

Detailed explanation-1: -It can take them upwards of 20 years to reach sexual maturity, and the female elephants, called cows, carry one offspring for nearly two years.

Detailed explanation-2: -K-selected reproductive strategies tend towards heavy investment in each offspring, are more common in long-lived organisms, with a longer period of maturation to adulthood, heavy parental care and nurturing, often a period of teaching the young, and with fierce protection of the babies by the parents.

Detailed explanation-3: -K-Selected Traits On the opposite end of the spectrum, K-selected species represent traits that are more indicative of a gradual but steady lifestyle. These organisms tend to reach sexual maturity late in life.

Detailed explanation-4: -K-selected species possess relatively stable populations fluctuating near the carrying capacity of the environment. These species are characterized by having only a few offspring but investing high amounts of parental care. Elephants, humans, and bison are all k-selected species.

Detailed explanation-5: -In biology, this is called r-K selection: in an r-situation, organisms will invest in quick reproduction, in a K-situation they will rather invest in prolonged development and long life. Typical examples of r-species are mice, rabbits, weeds and bacteria, which have a lot of offspring, but a short life expectancy.
