Final answer:
A Type I survivorship curve represents species like humans and most mammals where there is low infant mortality and a higher death rate among the older population.
Step-by-step explanation:
A Type I survivorship curve is characterized by low mortality among younger individuals and an increasing mortality rate among older individuals. This means that individuals in a population with a Type I curve are much more likely to survive to maturity and eventually die in their older years. Humans and most mammals, which usually produce fewer offspring and provide extensive parental care to their young, are prime examples of species following the Type I survivorship curve pattern. The curve on a graph would slope steeply downward mainly at the later stages of life, indicating that the number of individuals surviving drops significantly as they reach old age.
