Population Ecology: Age Structure and Survivorship Curves

An S-shaped curve is known as

• Exponential graph

• Logistic Graph

• Survivorship curves

• Graphs

Type 3 graphs show

• Some death rates

• Death rates through out

• Death rates at older ages

• High death rates at a young age

Type 1 curve represents what type of group

• Birds

• Humans

• Trees and plants

• Marine life

Emigration is

• the movement out of an area

• the movement into an area

• movement in and out of an area

• migration

During the week, why did we create quadrats and take pictures of the garden?

• to help check for biodiversity in the area

• it was a fun experiment

• to look for plant species

• to go outside

What are survivorship curves?

• curves that describe the number of survivors over time

• curves that tell us what the limiting factors are

• curve that tells us about the carrying capacity

• a curve

Why don't populations grow indefinitely?

• limiting factors

• only biotic factors

• only abiotic factors

• none of the above
