5. Describe and explain the shape of a survivorship curve for K-selected species. 6. Look at the survivorship curves below and describe a species that would fit each of the curves. A survivorship curve is basically a graph that shows the number of individuals of a species or a particular group that survive at each age. In simpler words, it traces the decline of a group of individuals over time. Survivorship curves help us to determine various evolutionary strategies of different species.

Survivorship curves for three species. Species A Species B, and Species C. Y-axis (Number surviving) is log scale. r-strategists are most likely to have survivorship curves like the one labeled: (select one) Species A O Species B Species Question 38 1 pts Carrying capacity MacBook Air 30 888 F4 DI FS Do 11 F2 3 4 5 CO 6 7 8 8 9 0 A survivorship curve is a graph showing the number or proportion of individuals surviving to each age for a given species or group (e.g. males or females). Survivorship curves can be constructed for a given cohort (a group of individuals of roughly the same age) based on a life table. There are three generalized types of survivorship curves: R-strategist species This picture represents a r-strategist species because mosquitos don't protect offspring for very long, they have small bodies, mature quickly, have short life spans, and have a type 3 survivorship curve. In this lesson #Regulation_of_Population & also #Survivorship_curves it's #Three_types & #R_K_Strategies are described in details.Link for #self_assessment_t 30.The survivorship curve of most animals in the Antarctic terrestrial biome is represented by (1)I only (2)III only (3)IV only (4)I and II only (5)II and III only 31.The survivorship curve of an r-strategist could be represented by 5.

What conclusions can you draw about the relationship between r/k strategists and survivorship curves? _____ _____ _____ 7. The floodplain on either side of a river is a volatile environment subject to frequent flooding. Would you expect plants that were r or k strategists to be Which type of survivorship curve can be depicted as a straight line (where mortality rates are roughly equivalent at all life stages)? Type II As human mortality is greatest during later life stages (and most children survive into adulthood), humans demonstrate a __________ survivorship curve. A survivorship curve is basically a graph that shows the number of individuals of a species or a particular group that survive at each age. In simpler words, it traces the decline of a group of individuals over time.

Explain which organisms, according to THIS graph, are r selected and/or k selected. What does parental care have to do with these curves?

Table 1: Life table for bullfrogs Table 2: Life table for squirrels A survivorship curve is a graph showing the number or proportion of individuals surviving to each age for a given species or group.

Graph 3 shows the relationship between density and net reproductive rate, illustrating an almost perfect negative correlation between the two variables Survivorship curves show the distribution of individuals in a population according to age. Type I survivorship curves are characterized by high survival in early and middle life, followed a rapid decline in survivorship in later life.Example: Humans Type II curves are an intermediate between Type I and III, where roughly constant mortality rate is experienced regardless of age.Example: Some birds In Type III curves, the greatest mortality is experienced early on in life, with …. Survivorship curve The overall survivorship curve for this population was similar to that of other marine mammals (Spinage 1972) (Figure 3).
