lag phase
How many types of survivorship curves are there?
1
2
3
4
Survivorship curve represented with low death rates during early and middle life, then an increase among older age groups, a good example are humans.
type I
type II
type III
type IV
Survivorship curve represented by a death rate that is constant over organism’s life span, squirrels and songbirds are good examples.
type I
type II
type III
type IV
Survivorship curve represented by high death rates for the young, then a slower death rate for survivors, good examples are fish and frogs.
