Survivorship curve k selected species
WebThis type of curve is characteristic of species that produce a large number of offspring (see r/K selection theory ). This includes most marine invertebrates. For example, oysters produce millions of eggs, but most larvae die from predation or other causes; those that survive long enough to produce a hard shell live relatively long. WebA lot of effort is invested in each individual, resulting in high survivorship throughout the life cycle: Most individuals die of old age. In general, this is more typical of K-selected...

Another thing these animals have in common is their K-selected life history traits. Why might they be more easily endangered than animals with r-selected life history traits? What general type of …
WebDec 27, 2024 · K-selected species members are much more likely to reach late adulthood than members of an r-selected species, who, on average, die much sooner. 3.3 Survivorship curves A survivorship curve is a graphical representation of the mortality rate of a population over time. WebA survivorship curve is basically a graph that shows the number of individuals of a species or a particular group that survive at each age. In simpler words, it traces the decline of a group of individuals over time. Survivorship curves help us to determine various evolutionary strategies of different species.
