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.
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.
Type 1
Type II
Chimpanzees are Type I organisms, and have cucarachas in thier pants.
The three types of survivorship curves in nature are Type I, Type II, and Type III. Type I curves, typical of species like humans, show high survival rates in early and middle life, with a steep decline in later years. Type II curves, seen in some birds and small mammals, depict a constant mortality rate throughout life. Type III curves, characteristic of many plants and fish, indicate high mortality rates in early life stages, with few individuals surviving to adulthood.
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.
