Examples of Animals with Type I Survivorship Curves

📚 Quick Study Guide

• 📈 Definition: Type I survivorship curves show high survival rates in early and middle life, followed by a rapid decline in later life.
• 👨‍👩‍👧‍👦 Parental Care: Animals with Type I curves often exhibit strong parental care, increasing offspring survival.
• ⏳ Lifespan: These organisms typically have longer lifespans compared to those with other types of survivorship curves.
• 🍎 Resource Investment: Significant energy investment into fewer offspring.
• 🌍 Examples: Prominent examples include humans, large mammals, and some plants.

🧪 Practice Quiz

1. Which of the following is characteristic of animals with Type I survivorship curves?
   1. High mortality rate early in life.
   2. Constant mortality rate throughout life.
   3. High survival rate throughout most of the lifespan, followed by a rapid decline.
   4. Low survival rate overall.
2. Which animal is a classic example of an organism exhibiting a Type I survivorship curve?
   1. Insects
   2. Fish
   3. Humans
   4. Sea Turtles
3. What is a key factor contributing to the Type I survivorship curve?
   1. Large number of offspring
   2. Minimal parental care
   3. Extensive parental care
   4. Early reproductive maturity
4. Which of the following best describes the reproductive strategy of organisms with Type I survivorship curves?
   1. Producing many offspring with low individual survival rates.
   2. Producing few offspring with high individual survival rates.
   3. Reproducing asexually at a rapid rate.
   4. Releasing eggs and sperm into the environment without parental care.
5. What type of environment is most likely to support a population exhibiting a Type I survivorship curve?
   1. Unstable and unpredictable environments
   2. Resource-scarce environments
   3. Stable and resource-rich environments
   4. Environments with high predator density
6. Which of the following is NOT typically associated with a Type I survivorship curve?
   1. Long lifespan
   2. High juvenile mortality
   3. Significant parental investment
   4. Delayed reproductive maturity
7. Which statement accurately reflects the relationship between lifespan and survivorship in Type I curves?
   1. Shorter lifespans are common due to high early mortality.
   2. Lifespan has no influence on the shape of the survivorship curve.
   3. Longer lifespans are characteristic, resulting in higher late-life mortality.
   4. Lifespan is variable and depends on environmental conditions.
