Question

Giant redwood trees have _______ mortality _________ in the ____________ stages of life. They therefore exhibit a ___________ survivorship curve.

A.
lower, early, type 1
B.
lower, early, type 3
C.
higher, older, type 1
D.
higher early, type 3

Answer 1

Option D. Giant redwood trees have higher mortality rate in the early stages of life. They therefore exhibit a type 3 survivorship curve.

Step-by-step explanation:

Giant redwood trees are those organisms which have a high mortality rate when they are young but once survive and reach adulthood, they can survive very long for a full lifetime.

These features matches with survivorship curve type 3 especially with K-type organisms like the forest trees which have high mortality rate when young, struggle to survive, but upon maturity have low mortality rate and survives relatively longer into adulthood. This is because of early reproductive stages along with rapid development.

Answer 2

D. higher, early, type III

Step-by-step explanation:

The Type III Survivorship Curve represents groups of few individuals or species that survive adulthood. These groups of species, once they survive growth, are able to get older without high risks as their death rate is high during their early months / years.

An example is the species of Giant Redwood trees. Many individuals exhibit higher mortality during the early stages of life. However, if they make it, they will survive for long periods of time. Therefore, they exhibit a type 3 survivorship curve.
