Why could organisms that use a K-selected life strategy be more at risk when environmental conditions change?

K-selection organisms have the maximum chance of surviving in the surrounding where the number of organisms is near the carrying capacity, however, the lack of offspring makes them endangered species.

Explanation:

K-species can give the offspring with the great possibility of surviving until mature.

K-selection is the most frequent in big animals, that have a long life span, and many generations that meet. K-selection organisms give less offspring but with a stronger organism.

However, these organisms are more endangered, as they tend to have fewer offspring, so their populations cannot recover as quickly from disorders such as excessive hunting or fire.

b. lithosphere, asthenosphere, mesosphere   is the answer most likely

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.
