The three types of curves are also described as: early loss, late loss, and constant loss. Propose an organism that would have a Type 2 curve. Defend your choice by describing this animal's life pattern using the data and growth curve as a guide. (If you are really stuck, use google to look up survivorship curves)

Question

The three types of curves are also described as: early loss, late loss, and constant loss. Propose an organism that would have a Type 2 curve. Defend your choice by describing this animal's life pattern using the data and growth curve as a guide. (If you are really stuck, use google to look up survivorship curves)

This graph represents three different types of survivorship curves, commonly used in ecology to describe the survival patterns of different species over time. **Axes:** - The vertical axis represents the "Percentage of organisms surviving," ranging from 0 to 100. - The horizontal axis represents "Time," showing how survival percentages change over time. **Curves:** - **Type 1 (Dashed line):** This curve is concave, indicating that most organisms survive into old age. This pattern is typical of species that have low mortality rates in early and middle life, followed by a sharp decline in older age. Humans and many other large mammals often exhibit this type of survivorship curve. - **Type 2 (Solid line):** Represented by a straight line, this curve indicates a constant death rate at all ages. This means the likelihood of death is approximately the same at any age. Many birds and some reptiles follow this pattern. - **Type 3 (Dotted line):** This curve is convex, showing high mortality in early life, but those that survive the early period live longer. This pattern is common in species that produce a large number of offspring and have little parental care, like many fish and invertebrates.
