Question

each type of curve represents a different reproductive strategy. some organisms have few offspring and most will survive. other organisms may lay thousands of eggs, only a few of which will survive to maturity. why is type i survivorship typical of humans and other large mammals? *academic vocabulary invertebrates animals, such as insects, without a backbone amphibians animals, such as frogs, that need water to reproduce 14.3 vocabulary check population density survivorship curve population dispersion fill in the blanks with the correct term from the list above. 1. is the number of individuals per unit of area. 2. a shows the number of organisms that survive over time. 14.3 the big picture 3. which type of population dispersion—clumped, uniform, or random—would be beneficial for a species in which competition for resources is high? explain. 4. what is one example of an organism with clumped dispersion? 5. what do the three types of survivorship curves represent?

Explanation:

1. Population density is defined as the number of individuals per unit of area.
2. A survivorship curve shows the number of organisms that survive over time.
3. Clumped dispersion would be beneficial as individuals can cooperate to access resources in high - competition situations.
4. Wolves often exhibit clumped dispersion as they live in packs.
5. Type I represents high survival until old age (e.g., humans and large mammals), Type II represents a constant death rate over time, and Type III represents high mortality early in life with few reaching adulthood.

Answer:

1. Population density
2. Survivorship curve
3. Clumped dispersion. In high - resource competition, individuals in a clumped pattern can cooperate to access resources, defend territory, and gain other survival advantages.
4. Wolves (living in packs)
5. Type I: High survival until old age; Type II: Constant death rate over time; Type III: High mortality early in life with few reaching adulthood.
