The three types of survivorship curves are type I, II, and III. Firts blank: Option B, convex curve. Second blank: Option A, humans.
Different species have survival curves differently shaped. In general terms, there are three different survival curves.
Mortality often occurs at the end of the cycle, representing species with low mortality.
Organisms exhibiting this type of survivorship curve have long cycles of life and high probability to survive until they are old enough.
These species have few descendants and spend too much time and energy in parental care to ensure their reproductive success.
The probabilities of dying are equal all along the cycle, at any age interval. The number of dead individuals remains constant from the beginning to the end of the life cycle.
These species have reduced offspring, and they ensure their reproductive success by providing some significant parental care.
Significant mortality during the early stages of life.
Only a few individuals reach the later life stages, getting to survive their first period of life.
Survivors usually have long life. These species produce big offspring at the same time, but they provide little or no parental care.
Their reproductive success relies on the number of descendants.
According to this information, we can complete the phrase.
A type I survivorship curve is a convex curve, and shows individuals that survive from childhood to adulthood.
The greatest number of deaths occurs during old age.
An example of a type I curve is seen in humans.
