Type 1 = high survivorship when young, and low at old age
Humans exhibit survivorship curve similar to that of K-selected species, which invest heavily in fewer offspring with higher parental care, resulting in a longer lifespan. Furthermore, humans also display characteristics of Type I survivorship curve, where most individuals survive to old age due to the high level of parental investment and social support.
type 1 curve is a more common curve for large mammals like humans where individuals mostly die later in lifetype 2 is a curve that affects small mammals like birds, insects, and reptiles that has a uniform rate of decline for lifetype 3 has a very high birth and mortality rate which makes a huge decline in the young population
Type I
A type 2 survivorship curve implies a roughly constant mortality rate across all age groups of the species.
Type 1
Type II
A survivorship curve is a graph that shows the pattern of survival in a population over time. It plots the proportion of individuals surviving at each age in the population. There are three main types of survivorship curves: Type I, Type II, and Type III, which represent different patterns of survival.
Chimpanzees are Type I organisms, and have cucarachas in thier pants.
type 1 is what it seems like but its type 2
Cheetahs exhibit a Type III survivorship curve. This means that they have a high mortality rate among the young, but those that survive their early years have a higher chance of living longer.
Opportunistic life history species are typically associated with a Type III survivorship curve, characterized by high mortality rates early in life and high reproductive output. This strategy favors producing a large number of offspring with minimal parental care to take advantage of unpredictable and unstable environments.
Many fish species and other species that have many offspring at once exhibit type the III survivorship curve, because most die early in life. Few live to old age, but most that survive their youth will live a long life. The organisms that exhibit this type of survivorship curve are typically r strategists, so they provide little to no parental care for their offspring, which makes it harder for them to survive, especially in the unusually unstable environments in which they may live.
