Survivorship Curves and Carrying capacity

On graph the x axis is

vertical

late loss

a large amount of the population that survives from birth to death

type I

dies at an old age

constant loss

death rate is the same throughout all parts of life

type II

constant loss

Early loss

A population dying at an early age

Type III

early loss

type I survived tho adulthood more than the other types

because they have great parental care which increases the chances .

type I would be a

k species because of the parental care

type III would have less chance of making it to adulthood than the other types

Because they provide no parental care so there is a high infant mortality

type III is r selected

because of their poor parental care (r or k)

what type and what species

type III - r selected

what type and what species

type I - k selected

survivorship curves

a graph that shows the percent survival rate for various age groups in a population from birth to maximum age for that species .

survivor ships gives insight on

whether a species is k or r selected and what type they are .

suvivorship graphs are used for

Ecologists for calculating the amount of females will survive to reproduction age . And utilize that data to figure out the population growth rate to help mange the species there.

Biotic potential

the maximum reproductive rate under perfect conditions

Carrying capacity

maximum number of organisms the environment can support without declining the resources

difference between carrying capacity and biotic potential

Biotic potential refers to the built in ability of a population to increase in numbers when the environment is perfect . While carrying capacity refers to the maximum population size that an environment can .

when a population goes over cc

there would be a dieback

catastrophic dieback

when a population sinks down far below its maximum following an overshoot

what type of species would grow at a rapid rate

r selected species have a rapid reproductive growth rate and are more likely to overshoot the carrying capacity.

what type of species would maintain population at carrying capacity

K selected because they’re better in stable environments .
