type 1 is what it seems like but its type 2
Type 1 = high survivorship when young, and low at old age
Type 1
Type I
A type 2 survivorship curve implies a roughly constant mortality rate across all age groups of the species.
Type II
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.
Chimpanzees are Type I organisms, and have cucarachas in thier pants.
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.
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.
Seagulls and other birds
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.
The survivorship curve that best represents the human life table is typically a Type I curve. This curve is characterized by high survival rates during early and middle life, with a significant drop in survival as individuals reach old age. In developed countries, this pattern reflects advancements in healthcare and living conditions that have increased longevity. However, in less developed regions, the curve may show elements of Type II or Type III, where mortality rates are higher in infancy or throughout life.
