Type I: Type I survivorship curves are characterized by high survival in early and middle life, followed a rapid decline in survivorship in later life.
Type II: Type II curves are an intermediate between Type I and III, where roughly constant mortality rate is experienced regardless of age.
Type III: In Type III curves, the greatest mortality is experienced early on in life, with relatively low rates of death for those surviving this bottleneck.
The three types of survivorship curves are Type I, which is characterized by high survival rates throughout most of the lifespan; Type II, which represents a relatively constant mortality rate over the organism's lifespan; and Type III, which features high early mortality rates and lower rates of mortality as individuals age.
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.
The three types of spatial distribution are uniform distribution (evenly spaced), random distribution (no pattern), and clustered distribution (grouped together).

A population's growth curve most closely resembles an "S" shaped curve, known as the logistic growth curve. Initially, the curve rises slowly as the population grows, followed by a period of rapid growth, before leveling off as the environment's carrying capacity is reached and growth stabilizes.
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 = high survivorship when young, and low at old age
Seagulls and other birds
Type I
A type 2 survivorship curve implies a roughly constant mortality rate across all age groups of the species.
Type II
Type 1
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.
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.
