In the real world, many organisms don't "fit" clearly into either the r-strategist or K-strategist category for Select one:

a. population reproductive strategies.

b. human growth factors.

c. population growth curves.

d. intrinsic reproduction.

a. population reproductive strategies.

Explanation:

Strategies K and r are closely related to reproductive strategy, habitat selection and the ability to disperse.

The organisms that reproduce by strategy r are small organisms that reach maturity in a short time, have short life periods, have numerous offspring (many of which fail to reach adulthood), devote little or no energy to breeding of the youngest of the species, they do not have mechanisms to limit their reproduction to the carrying capacity of their habitat, and tend to be opportunistic invading new areas and adapting to them easily. In this group are most insects, plants that reproduce by spores, turtles, toads and rabbits. The population of these species considered strategic r depends largely on how quickly they reproduce, and not on the carrying capacity of the habitat.

K strategists, on the other hand, are larger, mature very slowly, tend to live for a longer period of time, their offspring are more resistant to diseases, have few young, dedicate time and energy to raising children, they have mechanisms to limit their reproduction and adjust it to the carrying capacity of their habitat, and they remain in a particular habitat without invading those of other species.
