Question

Species with a type III survivorship curve are likely to exhibit:

Option 1: Fast population growth rate
Option 2: Large amounts of parental care
Option 3: Density-independent population regulation
Option 4: Both I and II

Answer 1

Species with a Type III survivorship curve tend to exhibit density-independent population regulation, characterized by very high initial mortality, low parental care, and large offspring numbers.

Step-by-step explanation:

Species with a Type III survivorship curve are characterized by having a very high death rate among the young, which decreases significantly for individuals that survive to older age groups. These species typically produce a large number of offspring but provide very little or no parental care. The absence of parental care results in many offspring not surviving to maturity, but because of the large numbers produced, some are likely to survive to adulthood. Based on these characteristics, the correct answer for the given options would be:

• Option 3: Density-independent population regulation

Option 1 (Fast population growth rate) and Option 2 (Large amounts of parental care) are not typically associated with a Type III survivorship curve. Instead, these characteristics align more closely with Type I survivorship curves, where there are fewer offspring with better chances of survival due to the high level of parental care.
